San Mai Knife – Böhler S290 Core & Stainless Damascus Cladding

San Mai Knife – Böhler S290 Core & Stainless Damascus Cladding
Stabilized Karelian Birch • Mammoth Tooth Spacer • Leather Sheath

A premium fusion of exotic materials, elite steel, and meticulous craftsmanship — this knife from Brothers Berezhnye stands out in both aesthetics and performance.

At its core is Böhler S290 — a high-speed powder metallurgy steel hardened to 67 HRC. With an ultra-fine microstructure and high-volume carbides, it delivers outstanding wear resistance, compressive strength, and edge stability. The chemical composition is precise and performance-driven:

• C 2.00 %

• Cr 3.80 %

• Mo 2.50 %

• V 5.10 %

• W 14.30 %

• Co 11.00 %

The cutting core is clad with hand-forged stainless Damascus steel, providing added durability and moisture resistance in the classic San Mai fashion.

The handle is crafted from stabilized Karelian birch, offering both resilience and the wood’s characteristic visual depth. A polished nickel silver bolster adds balance, while a unique mammoth tooth spacer contributes a natural, historical element. A mosaic pin and integrated lanyard hole enhance functionality and personalization.

Complimented by a hand-molded sheath made of vegetable-tanned leather—dyed in rich black and brown tones and featuring a free-hanging belt loop—the package exudes rugged elegance and practicality.
