Pocket Knife Guide: Types, Uses, and How to Choose the Right One

A pocket knife is one of the most useful tools you can carry — whether you’re opening packages, camping in the backcountry, or just need a reliable blade for everyday tasks. But walk into any gear store (or browse Velt Supply’s knives & tools collection) and you’ll quickly find dozens of different styles, blade shapes, and locking mechanisms. This guide breaks it all down so you can choose the right knife with confidence.

Folding vs. Fixed Blade: Which Do You Need?

Before diving into specific types, you need to answer one foundational question: folding or fixed blade?

Folding knives (pocket knives): The blade folds into the handle for safe, compact carry. Ideal for everyday carry (EDC), light tasks, and situations where a discreet carry is preferred. Legal in most places.
Fixed blade knives: The blade doesn’t fold. Stronger and easier to clean, making them better for heavy-duty outdoor and survival tasks. Typically carried in a sheath.

For most people, a quality folding pocket knife handles 95% of daily needs. Fixed blades shine for hunting, camping, and survival situations.

Common Pocket Knife Blade Shapes

The blade shape affects how the knife cuts, pierces, and holds an edge. Here are the most common styles:

Drop Point: The most popular EDC blade shape. A convex curve from spine to tip gives a strong, controllable tip great for slicing, skinning, and general use. The Swiss Army knife of blade shapes.
Clip Point: Features a concave “clip” cut into the spine near the tip, creating a thinner, sharper tip for piercing. Think classic Bowie knife style. Great for detailed work and hunting.
Tanto: Inspired by Japanese sword design. A thick, strong tip great for piercing hard materials. Popular in tactical knives. Not the best for slicing food, but extremely durable.
Wharncliffe: Straight cutting edge with a spine that curves down to meet it. Extremely precise tip — great for woodworking and detail cutting.
Sheepsfoot: Flat cutting edge, rounded spine curves down to meet it — no sharp tip at all. Designed for safety in rescue scenarios where you need to cut without risking a stab.
Spey Point: Small, dull tip with a curved blade. Originally designed for castrating livestock — now common in traditional multi-blade pocket knives.

Locking Mechanisms: How the Blade Stays Open

For any folding knife you plan to use with force, a reliable lock is essential. Here are the major lock types:

Liner Lock: A thin metal liner inside the handle springs into the blade’s path when open. One of the most common EDC locks — simple, reliable, and easy to close one-handed.
Frame Lock: Similar to a liner lock but uses the handle frame itself as the locking piece. Stronger than a liner lock — common on premium titanium and steel-handled knives.
Lockback: A spine-mounted rocker locks into a notch in the blade. Very strong and secure — requires two hands to close. The classic choice for traditional pocket knives.
Axis Lock (Benchmade patent): A spring-loaded bar runs across the width of the handle and locks into the blade. Extremely strong, ambidextrous, and smooth to operate one-handed. Found on Benchmade knives.
Button Lock: Press a button to release the blade. Often found on automatic (switchblade) knives where legal, or on higher-end assisted-opening folders.
Slip Joint: No lock — a spring tension keeps the blade open or closed. Traditional pocket knife design. Safe for carry but not ideal for heavy-duty work. Common on traditional multi-blade knives.

Blade Steel: What the Numbers and Letters Mean

Blade steel determines how sharp an edge gets, how long it holds that edge, and how resistant it is to rust. Here’s a quick reference:

420HC / 8Cr13MoV: Budget stainless steel. Easy to sharpen, corrosion resistant, but doesn’t hold an edge long. Good for casual users.
AUS-8 / VG-10: Mid-range stainless steel. Better edge retention than budget steels, still corrosion resistant. Popular on mid-priced EDC knives.
154CM / D2: High-performance steels common on USA-made knives. Excellent edge retention, tougher than VG-10, slightly more prone to rust (D2 especially).
S30V / S35VN: Premium stainless steel. Outstanding edge retention and toughness. The sweet spot for serious EDC users willing to pay more.
M390 / 20CV / 204P: Ultra-premium steels used on high-end knives. Exceptional edge retention and corrosion resistance. Harder to sharpen but stays sharp for months of hard use.

Handle Materials: Grip, Weight, and Durability

G-10 (fiberglass laminate): Lightweight, extremely durable, textured grip. The go-to material for serious EDC and tactical knives.
Carbon Fiber: Lightweight and premium-looking. Found on high-end knives. Less grippy than G-10 but strikingly beautiful.
Aluminum: Lightweight and strong. Anodized aluminum handles are popular on budget and mid-range folders.
Titanium: Premium, lightweight, corrosion-proof. Expensive but worth it for a lifetime carry knife.
Wood / Bone / Stag: Traditional materials with classic aesthetic. Found on traditional slipjoint folders and hunting knives.
FRN / Zytel (fiberglass-reinforced nylon): Lightweight and affordable. Used by Spyderco and other brands on lightweight EDC knives.

Pocket Knife Use Cases: Match the Knife to the Job

Everyday Carry (EDC): Drop-point or clip-point blade, liner or frame lock, 3–3.5 inch blade. G-10 or aluminum handle. Something you won’t mind scratching in a pocket.
Camping & Outdoor: Full-size folding knife or fixed blade, 4+ inch blade, drop-point shape, reliable lockback or frame lock. VG-10 or 154CM steel for rust resistance in wet conditions.
Hunting & Fishing: Drop-point or gut-hook blade, fixed blade preferred for butchering, stainless steel for corrosion resistance, comfortable handle grip.
Tactical / Emergency: Tanto or clip-point blade, strong frame or Axis lock, quick one-hand deployment (assisted opening), seat belt cutter or glass breaker combo tools.
Work / Utility: Simple, affordable folding knife or fixed blade with a replaceable blade system. Prioritize durability over premium materials.
