Hand-forged in the Batangas tradition
The balisong was born in Batangas, Philippines. Every knife in this catalogue is made by Filipino artisans and metalworkers, many from families with generations of experience, now working in the United States. Blades are ground from 440C stainless, D2 tool steel, VG10, high carbon and Damascus, and fitted to handles of kamagong ebony, carabao horn, Philippine deer horn and bone.
Checked four times
Detailed hand inspection, smoothness and pivot testing, blade alignment checks, and durability and finish quality control. If a knife doesn't meet our standards, it never reaches our customers.

An eel moves in one continuous line with no break in it. The BF-40 flips that way once the pivots warm up — 150g rolling through the transitions rather than jumping between them.

VG10 is a high-end Japanese stainless steel — roughly 1% carbon, 1% molybdenum, 15% chromium, 0.2% vanadium and 1.5% cobalt. Those small alloy additions are what give it its edge retention, wear resistance, corrosion resistance, hardness and toughness. It is a strong choice for knives used in humid conditions and is very popular in Japan, including with Japanese fishermen.
Handmade in the Batangas tradition and shipped from the USA. Our knife care guide covers keeping the pivots smooth and the blade protected; the rest of the range sits in the collection.
