SEKI KANETSUNE Matsu-Zumi-Yaki Santoku 170mm

Product Overview

The Kanetsune Matsusumi-Yaki series represents the pinnacle of Japanese bladesmithing, employing the rare and traditional pine charcoal quenching method. This unique heat treatment prevents decarburization, allowing the blade to achieve hardness comparable to Blue Paper Steel (Aogami) #2, despite being forged from White Paper Steel (Shirogami)#2. Crafted by an 80-year-old master artisan who has devoted his life to Echizen Uchihamono (Echizen Forged Blades), each knife is a one-of-a-kind work of art that embodies both strength and refinement.

Key Features 

Traditional Santoku Shape

The Santoku, meaning “three virtues” (meat, fish, and vegetables), offers a versatile profile with a wide blade and pointed tip—perfect for everyday kitchen tasks.

Matsusumi-Yaki Heat Treatment

Through pine charcoal quenching, the blade gains enhanced hardness and durability, surpassing the typical properties of White (Shirogami) #2 steel to rival Blue (Aogami) #2 in performance.

Superior Steel Composition

Forged from Takefu White Paper Steel (Shirogami) #2 and clad in multiple layers of softer steel, this construction delivers a razor-sharp edge with resilience and beauty.
