Nakiri bōchō (菜切り包丁, translation: knife for cutting greens) is a Japanese-style vegetable knives. They differ from the deba bōchō in their shape, as they have a straight blade edge suitable for cutting all the way to the cutting board without the need for a horizontal pull or push. These knives are also much thinner.
Nakiri bōchō are knives for home use, and sometimes have a black finished, or Kurouchi, blade. The cutting edge is angled from both sides, called ryōba in Japanese. This makes it easier to cut straight slices.
