A bunka pairs a flat profile with a sharp, angled tip, and this 175mm version from Yahiko is built for cooks who want push cutting precision along with some rocking versatility. The blade carries a deep kuro, or black, kurouchi finish layered over a hammered tsuchime texture, giving the knife a rustic look that also helps with food release.
The core is Aogami Super, one of the finest carbon steels available, prized for outstanding edge retention and sharpness, hardened here to about 63 HRC. The core is clad in stainless steel for added corrosion resistance, and the knife is finished with an upgraded octagonal handle in sakura, or cherry wood, paired with a black pakka wood ferrule. The even 50/50 grind suits both right and left handed cooks.
Care Instructions:Aogami Super is reactive and one of the hardest carbon steels around, so wipe and dry the blade immediately after each use rather than letting it sit. Avoid leaving acidic foods against the blade for long stretches, and apply a light coat of camellia oil for longer term storage. Hand wash only, and a quality water stone with a final strop will keep the edge at its sharpest between full sharpenings.
