Sukenari HAP40 240mm gyuto (custom handle with saya)

Specifications

The Sukenari 240mm Gyuto, crafted from HAP40 steel, is one of the hardest alloys used for kitchen knives. It features a minimalist aesthetic paired with outstanding performance. The intrinsic toughness of this powdered steel allows for far thinner grinding than other steels, while maintaining sharpness far longer than most others. If you’re looking for a Japanese knife with exceptional edge retention, the Sukenari HAP40 series is a top contender.

Sukenari Hamono, established in 1933, is a high-end professional knife manufacturer based in Toyama, Japan. Led by third-generation blacksmith Nobuo Hanaki-san, this small forge is renowned for its ZDP189 and Shirogami #1 Honyaki knives, along with its excellent grinding and highly consistent heat-treatment.
