How to Choose a Folding Knife: Steel, Handle, Lock and Size

Every knife in our folding range has a pivot, a lock and a pocket clip. Those three parts decide how it performs after the first week. This guide walks through the choices that actually matter when you buy one.

Folding knives built to be carried, not stored

Every knife on this page folds. That single fact decides most of what matters: it has a pivot, it has a lock, and it has to survive being carried in a pocket every day. We build around those three constraints rather than around how a knife looks on a shelf.

The range covers three broad jobs. Thin, light folders for everyday carry. Heavier frame-lock and crossbar folders for camping, hunting and field work. And pattern-welded Damascus pieces for people who want a knife that looks as considered as it cuts. If you are not sure which one fits, the sections below are the questions worth answering before you buy.

Start with the steel

Steel choice decides how long a blade holds an edge, how often you need to sharpen it, and how much care it needs between uses. There is no single best steel — only a trade-off between edge retention, toughness, corrosion resistance and sharpening effort.

D2 is a high-carbon tool steel with high chromium content. It holds an edge well and resists wear, but it is not fully stainless, so it wants a dry wipe and a light oil.
8Cr13MoV and 8Cr14MoV are stainless steels that resist rust and sharpen back quickly on a stone. A sensible choice if you maintain your own knives.
VG10 is a cobalt-alloyed stainless used widely in Japanese cutlery, with strong corrosion resistance and good edge holding.
M390 and S35VN are particle-metallurgy stainless steels. Powder metallurgy produces a finer, more evenly distributed carbide structure, which translates into consistent edge holding rather than a blade that dulls unevenly.
Damascus is pattern-welded steel — layers forge-welded into one billet. The figure you see is the structure of the steel, not a coating, so it cannot wear off.

Then the handle

The handle decides how the knife feels after an hour, not after a minute.

G10 is a glass-fibre laminate. It does not absorb water, does not swell, and stays textured when wet.
Carbon fiber is light and stiff, with a weave that shifts under light.
Aluminum gives rigidity without weight, and does not absorb anything.
Titanium alloy is light for its strength and immune to the corrosion that affects steel liners.
Wood, bone and antler are natural materials: warm in the hand, and each piece carries its own grain. They age into a patina rather than wearing out, but they need to be kept out of prolonged soaking.

The lock is a safety decision

A folding knife’s lock is what stands between a working edge and your fingers. All of the locks we sell are manual — you open the blade yourself, and you close it yourself.

Liner lock — a spring bar inside the handle moves across the blade tang. Simple, proven, one-handed close.
Frame lock — the same idea using the handle frame itself, which usually means a thicker, stiffer lock face.
Crossbar lock — a bar slides across the tang and releases with a thumb pull, so the blade closes without your hand leaving the handle.
Button lock — a button releases the blade with a press of the thumb, which matters when your other hand is occupied.

Blade shape: what each one is for

Drop point — a strong tip with a long curved edge. The most versatile shape, and the safest default.
Clip point — a concave spine near the tip for more piercing control. Common on hunting knives.
Tanto — a straight edge meeting an angled tip. A reinforced point and a long straight section for slicing.
Spear point — the tip sits on the centre line, so the blade tracks straight when pushed through material.

Size: 3 to 4 inches is the practical range

Blade length is usually the deciding number. Under three inches is easy to carry and legal in more places; three to four inches does real work without being awkward in a pocket; over four inches starts to need a reason. If you only own one folder, the middle of that range is where most people land.

How we check them

Every knife is inspected before it ships: blade play at the pivot, lock engagement, edge geometry, handle fit, and whether the blade sits centred when closed. We check pattern consistency on Damascus pieces by hand, because no two billets are the same.

Keeping it working

Wipe the blade dry after use. Keep a light film of oil on high-carbon and pattern-welded steels. Do not use a folder as a pry bar — sideways force is what chips edges, not cutting. Sharpen at a consistent angle and touch up often rather than grinding hard once a year.

Where to look next

If you want a blade that does not fold, see our fixed blade knives. If pattern-welded steel is what you are after, browse the Damascus collection. For a first folder, start with a D2 steel or M390 model in the three-to-four-inch range.
