A professional-grade gyuto for cooks who demand both edge longevity and visual distinction. Myojin Naohito hand-forges this COSP Gyuto from Cobalt Special Steel - a hard, semi-stainless alloy prized for its resistance to edge degradation - then finishes the handle in charred and lacquered oak. At 230mm, this is a workhorse blade with the character of a master craftsman's workshop. For cooks who appreciate the difference a hand-forged blade makes, this is that knife.
- Crafted by Naohito Myojin, a Tosa master whose finishing techniques are sought by bladesmiths across Japan
- Cobalt Special Steel (COSP) provides extreme hardness and long-lasting edge retention with semi-stainless properties
- Thin spine profile (2.3mm at heel, 1.4mm at tip) enables smooth, low-resistance cuts through proteins and vegetables
- 45mm blade width provides full knuckle clearance and a stable cutting platform for board work
- At 230mm, well-suited for slicing, breaking down large cuts, and extended prep sessions
- Charred and lacquered oak handle is heat-treated for durability with a refined, traditional appearance
- No dishwasher use - hand wash and dry immediately to maintain the blade
