The Bunka profile brings tip control and knuckle clearance together in a format that rewards confident, fluid knife technique. Myojin Naohito forges this COSP Bunka from Cobalt Special Steel - semi-stainless and intensely hard - then finishes it with a charred and lacquered oak handle that reflects the craft tradition of Tosa. At 165mm, it is a versatile everyday blade with edge performance equal to its visual character. Choose it and notice the difference every time you pick it up.
- Crafted by Naohito Myojin, a Tosa master whose finishing techniques are sought by bladesmiths across Japan
- Cobalt Special Steel (COSP) delivers extreme hardness with semi-stainless properties for long-lasting edge retention
- Bunka tip profile (angled spine, pointed tip) enables fine tip work, scoring, and detailed cuts
- Thin spine (2.1mm at heel to 1.45mm at tip) minimizes cutting resistance through a wide range of ingredients
- 40mm blade width offers knuckle clearance for comfortable board use
- 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
