Hand-Forged Karambit, Full-Hand Grip

Because the ring takes grip length away and something has to give it back. On a karambit the ring sits at the butt and your index finger goes through it, which means the ring occupies the part of the handle where the base of your hand would otherwise sit. On a compact karambit the result is that your remaining fingers get whatever is left, which for a lot of people is three fingers and a thumb jammed against the spine. Building the handle to eight inches against a six inch blade puts the whole hand back on the grip, with the ring as an anchor rather than an obstruction. The secondary effect is leverage: a hooked blade cuts by being pulled, and a longer handle behind the ring gives you a longer lever to pull with. The cost is bulk and a slower draw, which is set out honestly in the note near the top of this page.

This is the question to settle before you order anything with a ring on it, because a ring that does not fit makes the knife unusable rather than merely uncomfortable. Measure the second knuckle of your index finger, which is the widest part that has to pass through: wrap a strip of paper around it, mark where it overlaps, and measure the strip. A ring wants roughly two to four millimetres of clearance on that figure. Too tight and your finger will not pass through at all, or will not come out again in a hurry. Too loose is also a problem, because the knife rotates around a slack ring instead of being indexed by it, which is the whole reason the ring is there. Send us your measurement and we will forge the ring to it at no extra cost. If you would rather not measure, tell us glove size and whether you work gloved, and we will size sensibly from that.

Four builds, and they separate on how the knife meets your hand rather than on the blade. The Karambit, Full Tang is the standard proportion, a 7 inch blade at 14 inches overall with a single ring, and it is the one to take if you want a conventional karambit. The Claw Karambit is a shorter 6 inch blade with a deep hook and a ring pommel, the most aggressive cutter of the four on cord and strapping. The Double Ring Karambit adds a second ring through the blade for maximum retention, at the cost of locking your hand into one orientation. This one is the large-format build: the same deep hook on a handle two inches longer than the blade, for a full four-finger grip. Pick it if other karambits have felt too small in your hand, and pick one of the others if they have not.

Hook depth is the variable most buyers never think about and it changes what the knife is good at more than blade length does. A deep, tightly curved hook puts more of its edge in contact with whatever sits in the belly of the curve, and it closes around a rope or a strap faster, so the material is trapped and cut in a shorter pull. A shallower sweep needs a longer stroke to do the same work but will take something thicker, because the mouth of the curve is wider. This blade is at the deep end, which makes it fast on cord, twine, webbing, cable ties and garden growth, and poor on anything with real girth. If most of what you cut is thin and flexible, deep is what you want. If you are cutting hose, branches or heavy line, ask us for the shallower grind and we will draw the curve differently.

Because you cannot draw a ringed knife you cannot get a finger into first. On an ordinary knife you grasp the handle and pull, and a sheath that wraps the grip is no obstacle. On a karambit the first movement is threading your index finger through the ring, and that has to happen before the blade moves at all. A sheath that covers the handle makes the ring inaccessible and turns a one-second draw into a two-handed fumble. So a karambit sheath covers the blade, which is the part that needs covering, and holds the knife with a strap over the grip instead of by friction along its length. Release the strap, put your finger through the ring, and lift clear along the line of the curve. Do not try to pull it straight out.

Yes, and unusually you can check it yourself from the photographs, which is not true of most knives. The thin steel line running along the spine of the handle, between the two rosewood scales, is the tang itself. Follow it from the blade all the way to the ring at the butt: it is continuous, it does not narrow, and it does not disappear under the wood at any point. The scales are pinned through it with two pins, and the ring is part of the same piece of steel rather than a fitting attached to it. That is worth knowing as a general test on any full tang knife, because the claim is made constantly and the photograph either supports it or it does not.

Cord, rope, twine, webbing, strapping, sacking, netting, cable ties, packing tape and garden growth, all of which are pull cuts and all of which this shape does better than a straight knife. What it will not do is most other things. It will not slice food on a board, because a hooked edge cannot be laid flat against one. It will not carve, baton, spread or drill. It will not be thrust, because the point comes back toward your own hand. And it is a poor choice for anything thick, because the hook is deep and the mouth of the curve is correspondingly narrow. Buy it because you want a karambit, not as a general-purpose knife.

We cannot answer that for you and you should treat any seller who does with suspicion. What we can tell you is that this shape attracts more attention than most, because knife legislation often names features rather than types and a karambit carries two named features at once: a curved or hooked fixed blade, and a finger ring. Rules vary by country and, within countries, by state, province and city, and import rules differ again from carry rules. Check yours before ordering. If the ring is the problem, ask us for the plain-grip build at no extra cost. Our full tang karambit page covers how knife law treats blade shape in more general terms.

5160 high-carbon spring steel, the same stock our smiths use for kukris and swords, forged down from leaf spring in the Nepali tradition. It is oil-quenched and then tempered back, which gives a blade that holds a hard working edge but stays tough rather than brittle. It is not stainless. It will take a patina with use and it will rust if you leave it wet, which is the trade every high-carbon blade asks you to make in exchange for an edge that sharpens easily and cuts well.

Harder than the forge finish, yes, and worth knowing before you choose. A mirror polish is bare steel taken through progressively finer abrasives until the surface stops scattering light, so there is nothing between the steel and the air, and on high-carbon steel a fingerprint left on it will etch in within days. On a working knife that gets handled constantly, that is a real commitment. The dark forge finish costs the same, hides handling almost entirely and is what we would suggest if this is going to be used rather than displayed. Our wheel pommel dagger page explains the finish itself in more detail.

Not on a flat stone. A bench stone bridges a concave edge and touches only the two high points, so the hook flattens out over successive sharpenings and eventually stops being a hook, which on a curve this deep happens faster than on a shallow one. Use a round or tapered ceramic rod, a small-diameter sharpening steel, or a slip stone narrow enough to follow the arc, worked in short strokes along the curve and finished on the outside face to remove the burr. Our recurve knife page sets out the same problem in more detail, since it applies to any concave edge.

Close, but not identical, and that is the nature of forged work. The hook is drawn out by eye against a pattern, the grinds are done by hand, the ring is forged and filed individually, and rosewood varies board to board in colour and figure. What does not vary is the specification: length, steel, construction, heat treatment and sharpness are held to the same standard on every piece. Our kukri machete page explains in more detail what can and cannot differ between two blades from the same bench.
