The BF-02 Argentine Ant is a 22cm balisong with an 11cm blade, 175g, stainless bolsters with carabao horn. It is the cheapest 440C knife we make and the only one on a 22cm frame, which is the whole point of it.
Frame size is the decision most people get wrong
Buyers agonise over steel and then pick a size by accident. Size is the thing you will notice every single time you pick the knife up. Steel is the thing you will notice twice a year when you sharpen it.
| Open length |

Who it suits |
| 15cm |
Very fast, short arc |
Pocket carry. Not a learning knife |
| 22cm (this knife) |
Quick, still controllable |
Smaller hands, tighter spaces, people who found 24cm unwieldy |
| 24cm |
The standard. Balanced |
Most people, most of the time |
| 29cm |
Slow, deliberate, heavy |
Traditional size. Presence over speed |
Two centimetres does not read like much. Across a full rotation it changes the timing of every trick you know, which is why people who have flipped a 24cm knife for a year sometimes find this one briefly disorienting and then decide they prefer it.
Who this knife is actually for
Anyone whose hands are on the smaller side, and there are a lot of you. The standard 24cm frame is sized for an average adult male hand and if yours is not that, every rollover has been slightly more work than it needed to be. A shorter handle sits properly in the palm and the knife stops feeling like it is trying to escape.
It also suits anyone who flips in a room with furniture in it, which is most people.
175 grams on a short frame
That is a lot of weight for 22cm and it is deliberate. A short light knife is genuinely difficult, because it rotates fast and gives you almost no time to correct. Putting the weight back in slows the rotation down without adding length, which is the best compromise available on a small frame.
The stainless bolsters keep it at 175g. In brass the same frame would come out heavier and would have gone somewhere less useful.
440C steel on a butterfly knife, briefly
An American high-carbon stainless: about one percent carbon and seventeen percent chromium. That chromium is why it does not rust, and the carbon is why it hardens properly, which 440A and 440B do not. Anyone selling you “440 stainless” without the letter is telling you which one they bought.
Ours run at 58-60 HRC. It sharpens easily on any decent stone, holds an edge perfectly well for normal use, and asks nothing of you in damp weather. For a knife at this price that combination is the right answer.
Carabao horn as a balisong handle
Carabao is the Philippine water buffalo, and its horn is the original balisong handle material. The word itself probably comes from baling sungay, folding horn, which describes the handle and the mechanism in one go.
It is black to charcoal with occasional amber banding, harder and denser than deer horn, and it polishes to a genuine gloss. Keep it out of long direct sunlight and do not store the knife wet, and it will outlast you.
Trainer, sheath and shipping on this 440C butterfly knife
The unsharpened trainer is the same knife, selected above Add to Cart. Same steel, same horn, same 175g, no edge, same price, because grinding an edge is one operation in a build with many.
A fitted leather sheath comes with it, cut for this frame rather than the standard one. Free US shipping, flat $49 anywhere else for the entire order. Check your local knife law before ordering.
At 22cm the Argentine Ant is the smallest frame we sell in 440C, and how blade and handle length change the way a balisong feels lays out how that compares with our 24cm and 29cm builds. It belongs to the 440C butterfly knives. For anyone who wants the same steel and horn handle on the traditional full size frame, the BF-01 Bullet Ant is the one to look at.

Awesome craftsmanship on this one. Handles have a great grip even during fast flips. Pivots feel dialed in with zero blade play. Action is smooth right out of the box, no break in needed. Zero complaints from me on this purchase.
