Carbon steels which can successfully undergo heat-treatment have a carbon content in the range of 0.30–1.70% by weight. Trace impurities of various other elements can have a significant effect on the quality of the resulting steel. Trace amounts of sulfur in particular make the steel red-short, that is, brittle and crumbly at working temperatures. Low-alloy carbon steel, such as A36 grade, contains about 0.05% sulfur and melts around 1,426–1,538 °C (2,599–2,800 °F). Manganese is often added to improve the harden ability of low-carbon steels. These additions turn the material into a low-alloy steel by some definitions, but AISI’s definition of carbon steel allows up to 1.65% manganese by weight.

The handles carry kamagong — Philippine ironwood, one of the densest and most beautiful hardwoods on earth. At 24cm overall and 180g, it balances beautifully in the hand – built to the classic Filipino pattern.
Because every knife is handmade, small variations in grain and finish make each BF-76 Mayfly one of a kind. Explore the full authentic Filipino balisong collection, or make this one yours with custom engraving.
