Philippine Visayan Damascus Steel Blade Butterfly Balisong Knife USA Made Gift For Him With Beautiful Handle BF-123

The BF-123 is a Philippine Visayan balisong with a Damascus blade: 29cm open, a 14cm blade, 220g, brass with black micarta. Visayan smiths keep the profile long and the swedge clean, and the swedge is the detail worth a page because almost nobody knows what one is.

What a swedge actually is

A swedge is a bevel ground into the spine of a blade near the tip, on the unsharpened side. It is not an edge and it is not sharpened. It is a taper that removes steel from the back of the blade so the point comes to a finer conclusion than the thickness of the stock would otherwise allow.

Look along the spine of this knife from the handle toward the tip. For the last few centimetres the spine narrows on both sides. That is the swedge, and getting it symmetrical, evenly tapered and stopping at the same place on both sides is one of the fussier things a grinder does.

What it does, and what it does not

That last row is worth reading twice. A swedge is not a second edge and a swedged blade is not a dagger, but rules differ by jurisdiction and some define blades by shape rather than by whether they are sharpened. Check your own local rule rather than assuming.

Why Visayan blades run long and clean

The Visayan islands developed their own read of the balisong alongside Batangas, and the regional signature is a longer blade with a restrained profile. Less belly, a straighter spine, and a swedge that runs cleanly rather than being decorated.

On a 29cm frame with a 14cm blade that proportion reads as severe rather than ornamental, which is the point. This is not a knife trying to be pretty. It is trying to look like it means it.

The Damascus, and what it actually is on a butterfly knife

Layers of high carbon steel forge-welded together, folded, and drawn out. The pattern is the boundary between layers, revealed by etching because the different steels resist the acid at different rates.

Two consequences worth knowing. First, no two blades are the same, because the pattern depends on how that particular billet moved under the hammer. Second, this is high carbon steel, so it behaves like high carbon steel: it will spot if you leave it wet, and it wants a wipe when you put it down. There is no chromium in here doing you any favours.

Heat treated to 58-60 HRC. It takes a keen edge and comes back on an ordinary stone in minutes, which is the compensation for the maintenance.

Black micarta as a balisong handle

Micarta is layers of cloth or paper set in resin and cured under pressure. It is the newest material we work with on the oldest pattern we make, and we are not going to pretend that is traditional.

What it is: completely stable, immune to moisture, grippier than polished horn when your hands are warm, and it does not care about sunlight. On a knife whose blade needs looking after, a handle that needs nothing at all is a sensible pairing.

Two hundred and twenty grams on a 29cm frame

The traditional full size, called veinte y nueve in Batangas and built to the same length here. A longer handle sweeps a longer arc, so the rotation is slower and you get real time to correct a mistake. What it punishes is a loose grip.

Care, briefly

Wipe the blade dry every time you put it down. A light oil once a month. Do not store the knife in the leather sheath, because leather holds damp against steel and this is the steel that minds. The micarta needs nothing.
