Handmade Karambit Balisong Butterfly Knife | Satin Polished High Carbon Steel | Buffalo Horn and Bone Handle with Brass Frame and Leather Sheath BF-181

The BF-181 is a karambit balisong built the traditional Batangas way: a brass channel frame with blocks of buffalo horn and bone stacked inside it, and a brass ring at the end. $255.

How a sandwich handle is actually made

The brass is not a decorative strip. It is a folded channel, and it is the structural handle. The pivot goes through it, the ring is fixed to it, and everything it carries could be removed without the knife falling apart.

Inside that channel, blocks of material are stacked end to end and pinned through. Horn, then a thin slice of bone, then horn again. Each block is fitted individually, filed flush with the brass, then the whole assembly is finished as one piece so that your hand cannot feel the joins.

It is slow work and there is no way to speed it up, which is why almost nobody builds handles this way any more. Two flat panels screwed to a frame takes a fraction of the time.

Why the spacers exist at all

Originally, economy. Horn came in irregular pieces off an animal and long clean sections were the valuable ones. Building a handle from short blocks meant the offcuts became usable, and a pale spacer hid the join between two pieces that did not quite match.

The visual effect was a by product that turned out to be better than the intention. Alternating dark and light down the length gives the eye a rhythm and makes the handle read as longer and slimmer than a single block of the same size.

So a cost saving became a signature. That is how most good design happens and it is worth saying, because the alternative story, that somebody sat down and designed it, is usually a lie.

Two materials, two different care needs

In practice, handling the knife covers the horn’s needs on its own and the bone never asks for anything. The only real mistake is leaving it wet.

A satin blade, not a mirror

Satin is a directional finish, ground and then hand finished in one direction so the surface carries fine parallel lines. It sits between a mirror and a stone wash: brighter than matte, far more forgiving than a polish.

On a traditional handle it is the correct choice. A mirror would out shine the brass and turn the whole knife into a jewellery piece, which this is not.
