Kikuichi Kurouchi Petty Knife

The black oxide finish, or 'kurouchi' finish, serves as a protective layer for the high-carbon steel core. While it adds a distinct rustic aesthetic, it also helps reduce the reactivity of the steel, though you still need to keep the blade dry and clean to prevent rust.

If you are willing to commit to a simple maintenance routine, yes. Because this knife is made from White Carbon #2 steel, it requires you to wipe it dry immediately after every use and avoid leaving it in the sink. If you aren't prepared to hand-wash and dry it right away, a stainless steel alternative might be a better fit.

A 50:50 bevel means the edge is ground evenly on both sides, making it versatile for both right- and left-handed users. It is a standard, reliable grind that is straightforward to sharpen on whetstones.

No. The high-carbon steel core will rust quickly, and the natural walnut handle and water buffalo horn ferrule can crack or warp under the high heat and moisture of a dishwasher. Always hand-wash and dry this knife immediately after use.

A 6-inch petty knife is the perfect utility size for tasks that are too delicate for a large chef's knife but too involved for a paring knife. It excels at peeling fruits, trimming vegetables, slicing shallots, and de-boning small proteins.

Because the edge is made of high-performance carbon steel, it is prone to chipping if it strikes other metal utensils. We recommend storing it in a wooden knife block, on a magnetic strip, or in a dedicated blade guard to keep the edge protected.
