A flat, rectangular blade with a squared-off tip: the entire edge contacts the board at once in a downward push cut. There is no curved belly, no rocking, and no required forward or backward motion, only a vertical or angled-downward push. This produces extremely clean vegetable cuts with minimal bruising. For high-volume vegetable prep, a nakiri is faster and more efficient than a chef's knife or gyuto.
Primary tasks: vegetable preparation exclusively, including slicing, dicing, julienning, and chiffonade.
Ideal steel: thin blades reward reactive carbon steels that take a very fine edge, such as Aogami Super and Shirogami #1, or the stainless AEB-L; VG-10 for lower maintenance.
Limitations: protein slicing, bone work, and anything requiring a tip. It is the ideal second knife for a cook who already owns a gyuto or chef's knife.
Nakiri vs. usuba: the nakiri is double-bevel and accessible; the usuba is single-bevel and meant for advanced professional technique. Both cut vegetables, but only the nakiri suits home cooks.
