What Is a Fixed Blade Knife? Anatomy, Tangs, and Grinds

01 What is a fixed blade knife?

A fixed blade knife is a knife whose blade does not fold or retract — one continuous piece of steel running from tip through the handle, carried in a sheath rather than a pocket. With no pivot and no lock, there is nothing to loosen or jam, which is why hard outdoor work belongs to it.

Every moving part is a failure point. No pivot to loosen, no lock to test, no mechanism to pack with trail grit. The result is a knife that can be batoned through a log, dropped in a river, wiped on a trouser leg, and be ready for the next task before a folder has finished being unfolded.

The trade is carry: a fixed blade needs a sheath and a belt, a pack strap, or a neck cord. It announces itself. For the field, that trade is not a trade at all — it is the point. The fixed versus folding dossier draws the task line; this page stays on construction.

02 What is a full tang knife?

A full tang knife is one whose blade steel runs the entire length and width of the handle in a single piece, sandwiched between two pinned scales and visible as a spine along the handle's top and bottom. It is the strongest construction in knifemaking, and the only one we stock without reservation for hard outdoor use.

The alternatives exist to save weight or cost. A hidden (stub) tang extends partway into a solid handle — acceptable for light hunting knives, a gamble for batoning. A rat-tail tang narrows to a rod inside the handle — fine for letter openers, unforgivable in a "survival" knife. The rule is simple: if the knife might strike, pry, or split, the tang runs the full length or the knife stays in the store.

03 What are the different knife grinds?

The knife grinds you will actually meet are five: Scandinavian, flat, convex, hollow, and saber. A grind is the cross-sectional geometry between spine and edge, and it decides how a blade bites, slices, and survives — often more than the steel does. Each has a job, and the list below sets out what each one is for.

• ◆ Scandinavian (Scandi) — a single flat bevel from mid-blade to edge, no secondary bevel. The woodcarving king: bites deep, controls beautifully, and sharpens by laying the whole bevel flat on a stone — the easiest field sharpening there is.
• ◆ Flat grind — a flat taper from spine (or mid-blade) to edge. The generalist: strong enough for woodwork, thin enough for food prep, the default for good reason.
• ◆ Convex grind — a smooth curve to the edge, like an axe in miniature. The strongest edge of the three; superb for chopping and batoning, harder to sharpen without practice.
• ◆ Hollow grind — a concave curve, razor-thin behind the edge. The best pure slicer, and the most fragile at the edge. Belongs on skinners and kitchen knives, not on a blade that will meet knots and bones.
• ◆ Saber grind — a flat bevel starting mid-blade with a thick spine behind it. Durable, easy to sharpen, slightly crude at fine slicing. A thick-spine default on camp blades.

04 Matching grind to task

If the knife's main work is wood — feather sticks, notching, shelter building — the Scandi is the specialist's choice and the bushcrafter's religion. For a one-knife-does-everything camp blade, flat or convex. For a dedicated skinner where slicing is the whole job, hollow earns its fragility.

The honest summary: grind geometry decides more about daily behaviour than the steel name does. A Scandi in modest steel outcarves a hollow grind in premium steel, every day, at every woodpile.

05 Handles and scales: the part your hand votes on

Outdoors, the handle works wet, cold, and tired. Micarta — resin-soaked canvas or linen — grips best when wet and warms to the hand; it is the field standard for good reason. G10 is tougher, cheaper, and more aggressive in texture. Stabilised wood is beautiful and surprisingly durable, and what our heritage-leaning fixed blades wear. Rubberised synthetics grip superbly and age poorly.

Whatever the material, look for scales pinned — not merely glued — to the tang, with a handle shape that fills the palm without hot spots. A five-minute grip tells you more than a fifty-line spec sheet: hold it as if you were halfway through batoning a log, and the truth announces itself.

06 The sheath is half the tool

A fixed blade is carried in its sheath, so the sheath is carry hardware, not packaging. Kydex retains positively, drains water, and never rots. Leather is quieter, warmer, and traditional — but it holds moisture against the blade in long storage. Nylon is cheap, light, and the first part of a cheap knife to fail.

Check for positive retention — the knife should hold inverted with a shake — drainage at the tip, and a belt attachment that suits how you actually dress outdoors. A magnificent blade in a miserable sheath is a miserable knife. Sheath knives explained covers the three materials, the carry systems, and the four checks in full.

Frequently asked questions

Questions from the Counter

What is a fixed blade knife?

A knife whose blade does not fold or retract — one continuous piece of steel from tip through the handle, carried in a sheath rather than a pocket. With no pivot and no lock, it is the tool for camp, trail, and hard outdoor work. Shop the fixed-blade hub, priced in CAD.

How can I tell if a knife is full tang?

Look at the edge of the handle. On a full tang knife the blade steel runs the whole length and width of the grip, so a continuous spine of metal is visible sandwiched between two pinned scales. A partial or hidden tang disappears into the handle instead.

What is a Scandi grind good for?

Woodwork. The Scandinavian grind's single flat bevel bites into wood with superb control for carving, feather sticks, and notching, and it is the easiest grind to sharpen in the field — lay the whole bevel flat on a stone and stroke. It is the traditional bushcraft choice.

Is a hollow grind bad for outdoor knives?

Not bad — specialised. Hollow grinds slice superbly but run thin and fragile right behind the edge, so they chip more readily in hard tasks like batoning or bone work. They excel on skinning and kitchen knives; for a general camp knife, flat, convex, or Scandi grinds are sturdier.

Leather or Kydex sheath — which is better?

Kydex for function: positive retention, weatherproof, drains water, never rots. Leather for tradition, silence, and looks — but never store a blade in leather long-term, as it wicks moisture against the steel and invites rust.
