The Moritaka Custom line pairs the same Supreme blade construction - Aogami Super at 64-65 HRC, soft iron cladding, kurouchi finish, and an even 50/50 convex grind - with upgraded handle materials that are a step above the standard magnolia. This version features an oval bog oak handle. Bog oak is naturally dark and is dated to around 2,500 BC, giving the handle a deep, understated look that pairs beautifully with the black kurouchi cladding. CKTG is the exclusive US distributor of the Moritaka Supreme line. These blades are forged in Yatsushiro, Kumamoto Prefecture, where Moritaka Hamono has been making blades since the 13th century.
The 150mm petty with oval bog oak handle combines a versatile utility knife size with premium handle material. It is long enough for board work with smaller proteins, fruit, herbs, and vegetables, while still being compact enough for in-hand trimming and detail work. The Aogami Super core offers excellent edge retention and takes a very keen edge, while the kurouchi finish and convex 50/50 grind give the knife the rustic look and smooth cutting feel Moritaka is known for.
Care Instructions: Aogami Super is a reactive carbon steel and the soft iron cladding is also reactive, so both the edge and cladding will patina naturally with use. The kurouchi, or black as-forged finish, provides some initial protection, and the patina that develops over time adds further protection. Wipe and dry the blade immediately after every use. Avoid leaving acidic foods on the blade. Hand wash only; never put it in the dishwasher. Apply camellia oil for long-term storage. Sharpen on quality water stones. Aogami Super at 64-65 HRC rewards careful technique and responds beautifully to stropping. Keep away from bones, frozen foods, and hard materials.
