Take our KKFK00047 folding knife as an example. It’s a folding knife, a drop point knife, a manual-opening knife, a side-opening knife, and an EDC knife. Five different names for the same knife, and every one of them is correct.

That’s where pocket knife terminology can get confusing, especially when you’re buying your first knife or deciding which models to stock.

Pocket knives are classified by four main features: construction (folding or fixed blade), blade shape, opening mechanism, and lock type. A single knife can belong to several categories because each describes a different part of its design.

At Kegani, we manufacture knives with different blade shapes, locks, and opening mechanisms. In this guide, we’ll explain how these categories work, where they overlap, and how to choose the right combination for your needs.

Quick Facts: Pocket Knife Types

• 2 main construction types: Folding and fixed blade
• 9 common blade shapes: Including drop point, clip point, tanto, sheepsfoot, and Wharncliffe
• 3 main opening actions: Manual, assisted, and automatic
• 6 common lock mechanisms: Slip joint (non-locking), liner lock, frame lock, lockback, crossbar lock, and button lock
• 6 traditional pocket knife patterns: Trapper, Stockman, Barlow, Canoe, Congress, and pen knife

We’ll also cover how blade steel, intended use, and traditional knife patterns influence which pocket knife makes sense for you.

Pocket Knife Types at a Glance

The easiest way to choose a pocket knife is to start with what you’ll use it for. Different blade shapes, locking mechanisms, and steels suit different tasks, and some combinations are more practical than others.

Here’s a quick comparison of common pocket knife types and where each works best.

Best for	Knife type	Recommended blade shape	Lock type	Steel options
Everyday carry (EDC)	Manual or assisted folding knife	Drop point, sheepsfoot	Liner, frame, crossbar	14C28N, D2, S35VN
Hunting and field dressing	Locking folder or fixed blade	Drop point, clip point	Lockback (folders)	14C28N, S35VN
Camping and bushcraft	Fixed blade or heavy-duty folder	Drop point, spear point	Frame, lockback (folders)	14C28N, MagnaCut
Tactical and rescue	Manual, assisted, or automatic folder	Tanto, spear point, sheepsfoot	Crossbar, button, frame	D2, 154CM
Utility and work tasks	Manual folding knife	Sheepsfoot, hawkbill	Liner, lockback	8Cr13MoV, D2
Light-duty and traditional carry	Slip joint pocket knife	Pen blade, sheepsfoot	Slip joint (non-locking)	12C27, 14C28N
Collecting and gifting	Traditional or gentleman’s folder	Clip point, spear point, pen blade	Slip joint, lockback	S35VN, M390, Damascus

Our recommendation: If you’re unsure where to start, a manual folding knife with a drop point blade, a liner or crossbar lock, and 14C28N steel is a versatile choice for everyday use.

For retailers and knife brands, this table also provides a starting point for building a product range. You can cover several customer needs with a few carefully selected designs before expanding into specialized blade shapes or opening mechanisms.

Below, we’ll break down each category so you can understand the differences and make a more informed choice.

Folding and fixed blade knives

The first distinction between knife types is whether the blade folds into the handle or stays permanently fixed. Each design has its advantages depending on how you plan to use the knife.

Folding Knives

A folding knife has a blade that pivots into the handle when closed. Many models feature a locking mechanism to secure the blade during use, although traditional slip joint knives don’t have a true lock.

Folding knives are popular for everyday carry because of two main advantages:

• Portability: The blade folds into the handle, making the knife compact and convenient to carry in a pocket without a separate sheath.
• Versatility: Folding knives come in various blade shapes, opening mechanisms, and lock types, making them suitable for everyday cutting tasks.

Fixed-Blade Knives

A fixed-blade knife has a blade permanently attached to the handle. Its simple construction makes it a practical choice for demanding outdoor tasks where durability matters.

Fixed-blade knives offer three main advantages:

• Strength: A full-tang design, where the blade steel extends through the handle, provides greater structural strength for demanding tasks.
• Easy maintenance: With no pivot or locking mechanism, fixed blades are easier to clean, especially after outdoor use.
• Reliability: Fewer moving parts mean fewer mechanical components that could wear out or malfunction.

From a manufacturing perspective, the pivot and lock are additional points we need to account for when designing a folding knife. For demanding work such as batoning wood, a properly designed fixed blade is generally the better choice.

For a closer comparison, read our guide on fixed blade vs folding knife.

Types of pocket knives by blade shapes

Blade shape determines how a knife cuts, pierces, and handles different tasks. Some shapes are designed for everyday slicing, while others offer better tip strength, precision, or control.

At Kegani, we work with different blade profiles depending on the knife’s intended use. One thing worth understanding is that blade shape and blade grind are different. Shape describes the blade’s outline, while grind describes how the blade is tapered to form its cutting edge.

Here are nine common pocket knife blade shapes. For a more detailed comparison, see our guide to knife blade shapes.

1. Clip Point

A clip point blade has a section of the spine that appears cut away near the tip, creating a narrow, sharp point. This clipped section can be straight or slightly concave.

The fine tip makes clip point knives useful for precise cuts, piercing, and detailed work. You’ll commonly find this shape on hunting knives and traditional folding knives, including the well-known Buck 110.

Best for: Hunting, detailed cutting, and tasks requiring a precise tip.

Main drawback: The narrow tip can be more vulnerable to damage under sideways pressure.

Factory example: KKFK00013 Clip Point Folding Knife.

2. Drop Point

A drop point blade features a spine that gradually slopes downward toward the tip. This design leaves more material behind the point, providing a useful balance of tip strength and cutting control.

It’s one of the most versatile blade shapes for everyday carry. The curved cutting edge also provides enough belly for slicing, making it practical for food preparation, opening packages, and outdoor work.

Best for: Everyday carry, general utility, hunting, and outdoor activities.

Main drawback: The broader tip is less suited to fine piercing work than a clip point.

3. Spear Point

A spear point blade has a relatively symmetrical profile, with the spine and cutting edge tapering toward a centered tip. Some designs feature two sharpened edges, while others retain a single cutting edge.

The centered point makes this shape particularly effective for controlled piercing. Spear point blades also appear on tactical folders and certain traditional knife patterns.

Best for: Piercing, precision work, and tactical-style knife designs.

Main drawback: Depending on the design, the blade may have less cutting belly than a drop point.

4. Tanto Point

A tanto blade typically features a relatively straight main cutting edge that meets a shorter front edge at a distinct angle. This creates the recognizable angular point found on many modern tactical knives.

The geometry can leave substantial material behind the tip, helping it withstand demanding piercing tasks. However, the abrupt transition between the two edges can make continuous slicing and sharpening more challenging.

Best for: Utility tasks requiring a reinforced tip and controlled piercing.

Main drawback: The angular edge transition is less convenient for long, smooth slicing cuts.

5. Sheepsfoot

A sheepsfoot blade has a mostly straight cutting edge and a spine that curves downward toward a blunt or minimally pointed tip.

Its design reduces the likelihood of accidental piercing while providing excellent control for push cuts and straight slicing. This makes sheepsfoot blades popular for utility work and certain rescue applications.

Best for: Opening boxes, cutting rope, controlled slicing, and rescue tasks.

Main drawback: The blunt tip limits piercing and detailed point work.

6. Hawkbill / Talon Blade

A hawkbill blade curves downward like a bird’s claw, with the sharpened edge following the inside of the curve.

The curved profile helps catch and hold material during pulling cuts. That’s why this design works particularly well for cutting rope, cord, carpet, and other flexible materials.

Best for: Rope cutting, gardening, carpet cutting, and repetitive pulling cuts.

Main drawback: The curved edge is harder to sharpen with a standard flat sharpening stone and less versatile for general slicing.

7. Wharncliffe

A Wharncliffe blade has a straight cutting edge and a spine that gradually slopes downward to form a fine, pointed tip.

It’s often confused with a sheepsfoot blade, but there’s an important distinction: a sheepsfoot has a rounded, blunt tip, while a Wharncliffe has a sharper, more acute point.

The straight edge provides excellent control for detailed cutting, while the pointed tip is useful for precision work.

Best for: Whittling, opening packages, detailed cutting, and controlled utility tasks.

Main drawback: The fine tip can be vulnerable to damage during heavy-duty use.

8. Spey Blade

A spey blade typically has a relatively straight cutting edge with a short, rounded or clipped section near the tip. The shape was originally developed for livestock-related tasks where minimizing accidental punctures was important.

Today, spey blades are commonly found on traditional multi-blade pocket knives, particularly Trapper and Stockman patterns.

Best for: Skinning, controlled slicing, and traditional utility applications.

Main drawback: The rounded tip makes it unsuitable for tasks requiring precise piercing.

9. Pen Blade

A pen blade is a small, narrow blade commonly found on traditional pocket knives. It typically has a fine point and a relatively short cutting edge.

The name comes from its historical use in sharpening quill pens. Modern pen blades are useful for small cutting tasks that don’t require a full-sized blade.

You’ll often see them as secondary blades on traditional pocket knives.

Best for: Light-duty cutting, detailed work, and small everyday tasks.

Main drawback: The short blade limits its usefulness for larger or more demanding cutting jobs.

Ultimately, the best blade shape depends on the job. For general everyday carry, we typically recommend starting with a drop point. For controlled utility cuts, a sheepsfoot or Wharncliffe may be more suitable, while specialized tasks can justify a tanto, hawkbill, or other profile.

Types of Pocket Knives by Opening Mechanism

The opening mechanism determines how a pocket knife’s blade moves from the closed to the open position. Some knives require you to open the blade manually, while others use a spring to assist or complete the movement.

There are three main opening actions: manual, assisted, and automatic. You’ll also encounter terms like OTF, side-opening, and dual-action, which describe the direction or method of deployment.

1. Manual Opening

A manual-opening knife requires you to move the blade into its open position without spring assistance. It’s one of the most common mechanisms in everyday carry and traditional pocket knives.

Manual knives can use several opening methods:

• Nail nick: A small groove in the blade that allows you to pull it open, usually with two hands.
• Thumb stud: A raised post on the blade that allows one-handed opening.
• Thumb hole: A cutout in the blade that provides leverage for opening it with your thumb.
• Flipper tab: A protruding tab near the blade’s pivot that you press to rotate the blade open.

From a manufacturing perspective, smooth manual deployment depends on pivot tolerances, blade alignment, and the quality of the washers or bearings. A well-made manual folder should open consistently without excessive blade play.

2. Assisted Opening

An assisted-opening knife combines manual movement with spring assistance. You begin opening the blade using a thumb stud or flipper, and an internal spring helps complete the movement once the blade passes a certain point.

Assisted openers are popular among users who want quick, convenient one-handed deployment without relying on a fully automatic mechanism.

There’s also an important legal distinction. In 2009, the US Federal Switchblade Act was amended to exempt qualifying knives with a mechanism that biases the blade toward closure and requires manual force to overcome that resistance before opening assistance takes effect. This is why many assisted-opening knives are treated differently from switchblades under federal law, although state and local restrictions can still apply.

3. Automatic Opening

An automatic knife, commonly called a switchblade, uses a spring-loaded mechanism to deploy the blade when a button or switch is activated.

Unlike an assisted opener, you don’t need to push the blade partially open. The release mechanism triggers deployment directly.

Automatic knives offer convenient one-handed operation, but their internal mechanisms require careful attention to spring performance, reliable deployment, and secure blade engagement.

Keep in mind: Automatic knives face additional legal restrictions in many jurisdictions. Buyers and brands should verify applicable laws before purchasing, carrying, or importing them.

Factory example: KKFK00007 Folding Knife.

4. Dual-Action Opening

A dual-action opening mechanism allows a knife to be deployed in two different ways: manually or automatically.

For example, a dual-action folding knife may allow you to open the blade using a thumb stud or activate a separate button for automatic deployment.

This gives users more flexibility, although the additional components can make the mechanism more complex to manufacture and maintain.

It’s worth distinguishing dual-action opening from double-action OTF. The former offers manual and automatic opening methods, while the latter refers to an OTF mechanism that automatically extends and retracts the blade.

5. OTF and Side-Opening Knives

OTF and side-opening describe the direction in which a knife’s blade deploys.

Side-opening knives have a blade that rotates outward around a pivot. This includes most traditional folders, manual EDC knives, assisted openers, and many automatic knives.

OTF (out-the-front) knives deploy their blades straight out of the front of the handle instead of rotating sideways. Most modern OTF designs use automatic mechanisms, although manual OTF designs also exist.

There are two common automatic OTF configurations:

• Single-action OTF: A spring deploys the blade when activated, but the user must manually reset or retract the mechanism.
• Double-action OTF: A sliding switch automatically extends and retracts the blade, allowing one-handed operation in both directions.

Double-action OTF knives are mechanically more complex because the internal components must reliably control both deployment and retraction.

For a closer look at their construction and operation, read our guide on what an OTF knife is.

The opening mechanism you choose ultimately comes down to convenience, maintenance, and local regulations. For general everyday carry, a well-built manual folder is often sufficient, while assisted and automatic mechanisms appeal to users who prioritize faster deployment.

Types of Pocket Knife Locks

A pocket knife’s locking mechanism determines how the blade stays open during use and how you release it when you’re done. It’s an important consideration for safety, ease of operation, and the knife’s intended purpose.

There are six common pocket knife lock types worth understanding. Technically, a slip joint isn’t a true lock, but we’ve included it because it’s widely used in traditional pocket knives.

Lock type	How it works	One-handed closing	Common applications
Slip joint	Back spring provides resistance without locking the blade	Usually no	Traditional pocket knives, light-duty cutting
Liner lock	A spring-loaded metal liner engages the blade tang	Yes	Everyday carry, utility folders
Frame lock	Part of the metal handle frame engages the blade tang	Yes	Premium EDC, heavy-duty folders
Lockback	A spring-loaded rocker engages a notch in the blade tang	Usually no	Hunting knives, traditional folders
Crossbar lock	A spring-loaded bar slides into position behind the blade tang	Yes	Ambidextrous EDC knives
Button lock	A spring-loaded plunger engages the blade tang	Yes	Modern EDC folders, automatic knives

1. Slip Joint

A slip joint uses spring tension to hold the blade open, but it doesn’t mechanically lock it in place. The blade can close when sufficient pressure is applied.

You’ll commonly find this mechanism on traditional pocket knives, including Trappers, Stockmans, and Swiss Army-style knives.

Best for: Light-duty cutting, traditional designs, and users who prefer a simple mechanism.

2. Liner Lock

A liner lock uses a thin, spring-loaded metal liner inside the handle. When the blade opens, the liner moves behind the blade tang to prevent it from closing.

The modern liner lock was refined and popularized by knifemaker Michael Walker in the early 1980s, helping establish it as one of the most common folding knife locks.

We frequently work with this mechanism in folding knife designs because it provides reliable operation without requiring an overly complicated construction.

Best for: Lightweight EDC knives, general utility, and affordable folding designs.

3. Frame Lock

A frame lock operates similarly to a liner lock, except the locking bar is built directly into the handle frame rather than a separate internal liner.

Chris Reeve developed the Reeve Integral Lock in the late 1980s and popularized it through the Sebenza, introduced in 1990.

Frame locks are commonly found on titanium and stainless steel folding knives. Their performance depends on lock geometry, contact surfaces, and manufacturing tolerances.

Best for: Premium EDC knives and users who prefer a substantial metal-handle construction.

For a closer comparison, see our guide to frame lock vs liner lock.

4. Lockback

A lockback uses a spring-loaded locking bar along the spine of the handle. When the blade opens fully, the bar engages a notch in the blade tang to secure it.

Pressing the exposed section of the locking bar releases the blade so it can fold closed.

Lockback mechanisms have been used for generations, with the Buck 110 Folding Hunter, introduced in 1964, helping popularize the design in modern production knives.

Best for: Hunting folders, traditional locking knives, and users who prefer a straightforward locking mechanism.

5. Crossbar Lock

A crossbar lock uses a spring-loaded metal bar that moves into position behind the blade tang when the knife opens. Pulling the bar backward releases the blade.

Benchmade introduced its AXIS Lock in 1998, establishing the design that inspired many modern crossbar-lock mechanisms. With the original patents now expired, similar systems have become available across the knife industry.

Crossbar locks are particularly popular because they offer ambidextrous operation and allow users to keep their fingers away from the blade’s closing path.

Best for: Everyday carry, left-handed users, and anyone who values convenient one-handed operation.

Learn more in our guide to crossbar lock knives.

6. Button Lock

A button lock typically uses a spring-loaded plunger inside the handle to engage the blade tang. Pressing the button disengages the lock, allowing the blade to close.

Button locks appear on both manual and automatic folding knives, although the opening mechanism differs between the two.

Modern manual button-lock folders have become popular for their convenient operation. However, precise machining and consistent engagement are essential for reliable performance.

Best for: Everyday carry knives and users who prefer a simple, one-handed release.

Which Pocket Knife Lock Should You Choose?

For everyday use, liner locks, frame locks, and crossbar locks are all practical options. Slip joints suit lighter tasks and traditional designs, while lockbacks appeal to users who prefer an established locking mechanism.

From a manufacturing standpoint, lock design alone doesn’t determine strength or reliability. We also have to consider blade tang geometry, lock engagement, tolerances, and consistent operation across a production run.

A properly manufactured liner lock can be more reliable than a poorly executed frame lock. That’s why evaluating the finished mechanism matters as much as choosing the lock type.

For a more detailed breakdown of individual mechanisms, see our knife lock types guide.

Types of Pocket Knives by Use

Pocket knives are also categorized by what they’re designed to do. While many knives can handle multiple tasks, differences in blade shape, size, construction, and locking mechanisms make certain designs better suited to specific applications.

Here are five common categories based on how people use their knives.

1. Everyday Carry (EDC) Knives

Everyday carry (EDC) knives are designed for routine cutting tasks such as opening packages, cutting tape, trimming cord, and handling small repairs.

Most EDC knives are compact folders with blades around 2.5–3.5 inches long. They typically feature a pocket clip and a manual or assisted opening mechanism for convenient access.

• Recommended blade shapes: Drop point and sheepsfoot for versatile cutting.
• Common locks: Liner lock, frame lock, and crossbar lock.
• What to prioritize: Comfortable grip, manageable weight, smooth opening, and easy maintenance.

For most users, we’d recommend starting with a manual drop point folder. It handles common cutting tasks without adding unnecessary mechanical complexity.

2. Hunting Knives

Hunting knives are designed for field dressing, skinning, and processing game. These tasks require controlled cutting, a comfortable grip, and a blade that can be cleaned thoroughly after use.

Although fixed blades are generally preferred for demanding hunting applications, folding hunting knives remain popular because they’re easier to carry.

• Recommended blade shapes: Drop point for controlled skinning and clip point for detail work.
• Common locks: Lockback and frame lock on folding models.
• What to prioritize: Edge retention, corrosion resistance, grip security, and ease of cleaning.

For folding hunting knives, we generally favor designs with secure lock engagement and minimal areas where dirt or organic material can accumulate.

3. Camping, Bushcraft, and Survival Knives

Camping and bushcraft knives handle a wider range of outdoor tasks, including preparing food, cutting rope, carving wood, and making kindling.

Fixed blades are usually the better option for demanding wood-processing tasks. However, a sturdy folding knife can be useful for lighter camp chores or as a backup tool.

• Recommended blade shapes: Drop point for versatility and spear point for general utility.
• Common locks: Frame lock or lockback on folding models.
• What to prioritize: Blade toughness, secure grip, corrosion resistance, and ease of sharpening.

If you regularly process wood or use a knife for demanding outdoor work, we’d recommend a full-tang fixed blade rather than relying on a folding mechanism.

4. Tactical Knives

Tactical knives are commonly associated with military, law enforcement, and emergency-response applications. Their designs typically emphasize secure handling, accessible opening mechanisms, and dependable operation.

Many tactical-style folders also serve as general utility knives, although their appearance alone doesn’t determine their suitability for professional use.

• Recommended blade shapes: Tanto and spear point for specialized tasks; sheepsfoot for certain rescue applications.
• Common locks: Frame lock, crossbar lock, and button lock.
• What to prioritize: Reliable deployment, secure grip, lock engagement, and operation while wearing gloves.

Some models also include rescue-oriented features such as seatbelt cutters or glass breakers.

Automatic opening mechanisms may be useful in certain professional settings, but legal restrictions vary by location.

5. Multi-Tool Pocket Knives

Multi-tool pocket knives combine a cutting blade with additional implements such as screwdrivers, scissors, bottle openers, saws, or pliers.

Swiss Army-style knives and plier-based multi-tools are two familiar examples. They’re particularly useful when carrying several separate tools would be inconvenient.

• Common blade shapes: Spear point, pen blade, and other compact utility profiles.
• Common locking systems: Slip joints, backsprings, or dedicated locks on individual tools.
• What to prioritize: Useful tool selection, compact dimensions, accessibility, and durability.

The main trade-off is blade performance. Multi-tool blades are often smaller and less comfortable for prolonged cutting than dedicated pocket knives.

For occasional repairs, travel, and general everyday tasks, though, the convenience of having several tools in one package can outweigh those limitations.

The right category ultimately depends on how frequently you’ll use the knife and the demands of the task. An EDC folder suits most routine cutting, while hunting, bushcraft, and professional applications may justify more specialized designs.

Traditional Pocket Knife Patterns and Famous Knives

Before modern folding knives became popular, pocket knives were commonly identified by their traditional patterns. These patterns describe a knife’s handle shape, blade arrangement, and original purpose.

Many traditional pocket knives feature two or three blades, allowing users to perform different tasks without carrying separate tools. Most use slip joint mechanisms rather than modern locking systems.

1. Trapper Knife

The Trapper is one of the most recognizable traditional pocket knife patterns. It typically features two blades mounted at the same end of the handle:

• Clip point blade: Used for detailed cutting and general utility.
• Spey blade: Traditionally used for skinning and livestock-related tasks.

The combination made Trapper knives practical for hunters and outdoor workers. Today, they’re also popular among collectors and people who prefer classic pocket knife designs.

2. Stockman Knife

A Stockman typically features three blades: a clip point, a sheepsfoot, and a spey blade.

Each blade serves a different purpose, giving users more flexibility without requiring multiple knives.

• Clip point: General cutting and detail work.
• Sheepsfoot: Controlled slicing and straight cuts.
• Spey: Skinning and tasks where a less pointed tip is useful.

The Stockman remains a practical choice for users who appreciate traditional craftsmanship and multiple cutting options.

3. Barlow Knife

A Barlow is a traditional folding knife recognized by its elongated bolster, usually fitted at the pivot end of the handle.

Most Barlow knives feature one or two blades, commonly a clip point or spear point paired with a smaller pen blade.

The pattern became popular as an everyday working knife because of its straightforward construction and practical handle design.

Today, Barlow knives are especially appealing to collectors and brands developing heritage-inspired pocket knife collections.

4. Canoe Knife

The Canoe gets its name from its symmetrical, canoe-shaped handle, which typically curves upward at both ends.

Most designs feature two blades mounted at opposite ends, commonly a larger spear point and a smaller pen blade.

The rounded handle makes the knife comfortable to carry, while the two blades provide options for general cutting and finer work.

Canoe knives are a popular choice for traditional pocket knife enthusiasts who prefer compact, balanced designs.

5. Congress Knife

The Congress knife has a distinctive curved handle with a shallow concave section along one side.

Traditional Congress patterns commonly feature four blades, although two-blade versions also exist. Depending on the model, these may include sheepsfoot, coping, spear, or pen blades.

The multiple blades make the Congress useful for detailed cutting, carving, and light utility tasks.

Its unusual handle shape and blade arrangement also make it recognizable among collectors.

6. Pen Knife

A pen knife is a small, slim folding knife traditionally used for trimming and sharpening quill pens.

Most pen knives have one or two short blades, often with a simple slip joint mechanism.

Their compact size makes them suitable for opening letters, trimming small materials, and other light-duty tasks.

Today, the term penknife is sometimes used more broadly to describe small folding pocket knives, particularly in British English.

Why Do Traditional Pocket Knives Have Multiple Blades?

Traditional multi-blade knives developed when people often relied on one pocket knife for several jobs.

A farmer or tradesperson could use one blade for rough cutting, another for detailed work, and keep a third blade sharp for tasks requiring a cleaner edge.

That arrangement still has practical value. For example, a Stockman lets you switch from a sheepsfoot to a clip point without changing tools.

For knife brands, traditional patterns also offer opportunities to differentiate products through handle materials, bolster finishes, and blade combinations while retaining a familiar design.

Other Famous Knife Types and Names

Beyond traditional patterns, you’ll encounter several knife names based on historical origins, blade geometry, or opening mechanisms.

Some are folding pocket knives, while others are fixed blades or specialized designs.

Knife type	Defining characteristics	Common applications
Balisong (butterfly knife)	Two rotating handle sections that enclose the blade when closed	Collecting, manipulation practice
Bowie knife	Large fixed blade, commonly featuring a pronounced clip point	Outdoor utility, collecting
Dirk	Traditional long-bladed knife associated with Scotland	Historical collections, ceremonial use
Stiletto	Narrow blade with an acute point, often associated with Italian designs	Collecting, historical designs
Karambit	Curved, claw-like blade, often with a finger ring	Specialized cutting, martial arts
Navaja	Traditional Spanish folding knife, often with a distinctive curved handle	Collecting, traditional utility
Gentleman’s knife	Compact, refined folder, often featuring decorative handle materials	Light everyday carry, gifting
Gravity knife	Blade deploys using gravity or inertia after a release mechanism is disengaged	Specialized utility, collecting

A few of these deserve additional clarification.

Balisong knives, also called butterfly knives, use two handle sections that rotate around the blade tang. Their unusual opening mechanism distinguishes them from conventional folding knives.

Karambits are recognizable by their curved blades and frequent use of a retention ring. They can be manufactured as either folding or fixed-blade knives.

Gravity knives use gravity or inertia to deploy the blade once released. Their legal classification can vary by jurisdiction, so they shouldn’t automatically be grouped with conventional manual or automatic folders.

For buyers and collectors, understanding these names helps distinguish actual construction differences from historical or stylistic labels. A Bowie describes a recognizable knife style, for example, while a frame lock describes a specific locking mechanism.

Pocket Knife Steels at a Glance

The steel used in a pocket knife affects its edge retention, toughness, corrosion resistance, and ease of sharpening. At Kegani, we help buyers select steel based on the knife’s intended use, target price, and production requirements, while also considering heat treatment and hardness (HRC).

Steel tier	Common steel types	Key characteristics	Best for
Budget	3Cr13, 8Cr13MoV, 420HC, AUS-8	Generally easy to sharpen, with edge retention and corrosion resistance varying by alloy and heat treatment	Promotional knives, entry-level EDC, high-volume product lines
Mid-range	D2, 14C28N, Nitro-V, 154CM, VG-10	Better performance options across edge retention, toughness, and corrosion resistance; D2 needs more corrosion care	Everyday carry, hunting folders, outdoor utility knives
Premium	S30V, S35VN, M390, 20CV, MagnaCut, K390	Specialized performance, including high wear resistance or balanced toughness and corrosion resistance, depending on the alloy	Premium EDC, flagship knife collections, specialized applications

Our recommendation: For a new pocket knife line, 14C28N is a practical starting point for balanced performance, while D2 suits buyers prioritizing wear resistance at a competitive price. Premium steels such as M390 and MagnaCut make more sense when customers value their specific performance advantages and the higher manufacturing cost is justified.

Are All Pocket Knife Types Legal?

No, pocket knife laws vary depending on the knife’s opening mechanism, blade length, and where you live, with different rules sometimes applying to ownership, carrying, and selling.

In the US, manual folding knives and slip joints are generally less restricted, while qualifying assisted-opening knives are exempt from the federal switchblade definition under a 2009 amendment. Automatic knives, OTF knives, butterfly knives, and gravity knives may face additional restrictions under state or local laws; for example, California restricts switchblades with blades two inches or longer.

Before buying, carrying, or importing a knife, check the applicable regulations in your jurisdiction, as our overview isn’t legal advice. For more details, read our guide to pocket knife laws.

Which type of knife is best for you?

The right pocket knife depends on how you intend to use it. For individual buyers, blade shape, portability, and ease of operation usually matter most. For retailers and knife brands, it’s also worth considering customer demand, manufacturing costs, and how different models fit into your product range.

Here’s what we’d recommend for different types of buyers:

• For everyday users: Start with a manual folding knife featuring a drop point blade and a liner or crossbar lock. It’s a versatile combination for opening packages, cutting cord, and general utility work.
• For outdoor and camping retailers: Consider drop point hunting folders, lockback knives, and fixed blades made from practical steels such as 14C28N. Prioritize comfortable handles, corrosion resistance, and durability.
• For EDC gear stores: Stock a focused selection of manual folders with different blade shapes and locking mechanisms. Drop point liner locks can serve as an accessible starting option, while crossbar and titanium frame-lock designs appeal to buyers seeking additional features.
• For promotional product businesses: Existing folding knife designs with custom logos, finishes, and packaging are usually more practical than developing an entirely new model. Steels such as 8Cr13MoV can help keep production costs manageable.
• For new knife brands: We’d recommend starting with one proven folding knife platform, such as a drop point liner-lock or crossbar-lock design. You can differentiate it through blade steel, handle materials, finishes, and branding before investing in more complex custom tooling.

From our manufacturing perspective, one common challenge with new knife projects is trying to introduce too many designs at once. Each additional blade shape, lock type, or handle configuration introduces more specifications to verify and potential quality-control issues.

We generally recommend establishing a reliable base design first, with consistent heat treatment, blade centering, lock engagement, and overall fit and finish. Once the initial product performs as expected, it’s easier to expand the collection around actual customer demand.
