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.
Engraving available
Select the engraving option on the product page, then email your logo file with your order number to sales@balisongbutterfly.com.
A sheath with every knife
Every knife includes a fitted leather sheath. Both live blades and trainers are offered, and every order ships worldwide with tracking.
A caterpillar moves in one long, deliberate ripple rather than a jump. The full-size BF-20 flips much the same way — the 29cm frame carries a rollover through instead of snapping it short.

440C sits at the top of the 400-series stainless steels for carbon content — roughly 0.95–1.20% carbon, 16.00–18.00% chromium, 0.75% molybdenum, 1.0% manganese and 1.0% silicon. Heat treatment usually brings it to 58–60 HRC, and it can be oil quenched to reach maximum hardness. It is a bearing steel, long used for knife blades.
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.
