Louis Martin Custom Knives

Handmade Butterfly Knives

Quick Answer

A butterfly knife (balisong) is a folding knife with two counter-rotating handles that conceal the blade when closed. The handles fan open in a distinctive flipping motion. Louis Martin butterfly knives are handcrafted with Damascus and high-carbon steel blades.

The butterfly knife is as much a performance art tool as it is a knife — its distinctive flipping action has spawned an entire subculture of enthusiasts and competitors. Louis Martin's handmade balisongs are crafted for collectors who demand Damascus-quality blade work in this unique format.

Characteristics & Construction

Handle Construction

Our butterfly knife handles are precision-fitted with phosphor bronze washers at the pivot for smooth, consistent action. Handle scales in G10, titanium, and exotic wood offer diverse aesthetic options.

Blade Options

Damascus, D2, and 440C stainless blade options. Damascus butterfly knives are especially striking when the pattern is revealed through the flipping motion.

Care & Maintenance

  1. 1

    Lubricate pivots

    Apply a drop of light oil to both pivots monthly. Over-lubrication attracts lint; use sparingly.

  2. 2

    Check pivot tightness

    Pivots should be snug with smooth action. Loose pivots cause handle slap; overly tight pivots prevent smooth flipping. Adjust with the appropriate pivot screw tool.
