67-Layer Stainless Damascus San Mai Billet – Ladder Pattern – Pre-Hardened 58–60 HRC

67-Layer Stainless Damascus San Mai – Ladder Pattern

Pre-hardened San Mai knife steel with a hard stainless steel core clad on both sides with 67-layer stainless Damascus in a classic Ladder pattern.

The San Mai construction gives you a solid core running through the centre of the billet to form the cutting edge, while the stainless Damascus cladding creates the decorative pattern on the sides of the finished blade.

Made from 9Cr18MoV and 10Cr15CoMoV stainless steels, this billet is supplied already hardened and tempered to approximately 58–60 HRC, making it ready for stock-removal knife making without additional heat treatment.

The Ladder pattern features repeating lines running across the Damascus cladding, creating a bold pattern that becomes more pronounced as the blade is ground, finished and etched.

Cut out your blade profile, grind the bevels, finish to your preferred grit and etch to bring out the contrast in the stainless Damascus cladding. Keep the steel cool while grinding to avoid affecting the existing heat treatment.

As this steel is already hardened, drilling and machining will be more difficult than with annealed steel. Use suitable tooling and keep the billet cool during grinding.

Pattern placement and appearance will vary slightly from billet to billet.
