The Yamashin Blue #2 bunka is sometimes described in the original copy as a hakata, the regional name for a tall, forward-weighted bunka profile with origins in Hakata, northern Kyushu. Kaki-san hammer forges this in Tosa in a san mai construction with a Hitachi Blue #2 core and reactive soft iron kurouchi cladding.
At 180mm blade length and 50mm tall this is a substantial bunka with real board presence. The kurouchi finish on the soft iron cladding will patina and develop character with use, and the red sandalwood handle with colored pakka wood ferrule gives it the same warm look found across the Yamashin Blue #2 kurouchi line.
Care Instructions: Blue #2 carbon steel is reactive, so the entire blade - both the core edge and the soft iron cladding - will develop a natural patina with use. Wipe and dry the blade immediately after use, avoid leaving acidic foods against the blade, and apply a light coat of camellia oil for longer term storage. Hand wash only.
