Ultra-thin, laser keen and cloaked in a rustic kurouchi finish, this 165mm bunka glides through vegetables, proteins and herbs with remarkable ease. The satin-polished edge of Blue #2 steel peeks from beneath its dark iron cladding, while a rapid distal taper—from roughly 5mm at the heel to just over 1mm at the tip—delivers outstanding agility and surgical precision. A modest 44mm blade height offers knuckle clearance, and the light 124 g balance makes long prep sessions effortless.

Kurouchi by Kyohei Shindo is forged entirely by the smith in his Tosa workshop. Shindo-san layers Hitachi Aogami A2/S with soft iron using the traditional warikomi (san-mai) method, then hand-grinds an extremely thin “S-style” convex profile for silky push-pull cuts and excellent food release. Heat-treated to 62–63 HRC, the blade marries the edge retention of high-carbon steel with straightforward sharpening.

Kyohei Shindo 新藤京平 is part of a new wave of independent smiths keeping Tosa’s free-forging tradition alive. After eight years of training and a stint in cutlery retail, he opened his own forge in 2020, quickly earning a cult following for knives that “glide through food as if it isn’t there.”

Bunka 文化 translates to "culture" and represents a versatile Japanese profile that blends the best of santoku and kiritsuke. The angular K-tip excels at detail work on meat and fish while the tall heel powers through push-cut vegetable prep. This multi-tasker combines the nimbleness of a petty with the power of a gyuto, making it perfect for tight prep stations and home kitchens that want one knife to do it all with a bit of edge.

San Mai 三枚 means "three layers" — a hard cutting core sandwiched between two softer outer layers. This traditional construction protects the delicate edge from shock while adding toughness and simplifying maintenance, so you can enjoy the performance of high-carbon steel worry-free.

Aogami A2/S 青紙 (Blue Paper No. 2) is essentially white carbon steel enhanced with chromium and tungsten for added toughness. With 1.05 – 1.15% carbon plus tungsten (1 – 1.5%) and chromium (0.2 – 0.5%), this very hard Hitachi steel delivers exceptional edge retention and fine grain structure. Takes a razor-keen edge, sharpens effortlessly on whetstones, and rewards proper care—hand wash, dry immediately—with decades of superior performance.
