Hand-forged by Daisuke Nishida in Kumamoto, Japan, this 110mm petty knife has a shirogami core at ~62 HRC with soft iron cladding and a kurouchi finish. Petty knives handle the detail work: peeling, trimming, and any task where a larger blade gets in the way. The whole blade gains character as it patinas over time. Shirogami takes a keen edge and sharpens easily on stones. A Japanese utility knife for cooks who want a nimble carbon steel blade for detail work.

Daisuke Nishida is a blacksmith based in Kumamoto, Japan. He began his apprenticeship at 19, trained for nine years, and opened his own workshop in 2006. With nearly three decades in the craft, he works predominantly with Shirogami steel and uses hand forge-welded warikomi construction. Nishida-san forge-welds his own material and builds each knife from there. His knives lean toward a workhorse grind: good heft and enough meat behind the edge that makes the knife feel authoritative and not delicate.

Why is the blade length different from the displayed size? The size in the product title is a nominal reference used by knife makers. The actual blade can be slightly longer or shorter due to handcrafting and traditional sizing. Each product page lists the exact measured length.
