Nakiri

The Nakiri (literally "knife for cutting greens") is a Japanese kitchen knife with a thin blade for cutting vegetables without pushing or pulling.

The thin, straight blade cuts all the way to the cutting board in one vertical motion without breaking ingredients. Typically, the knife has a slight chisel grind on the front side, and a hollow grind on the back. This clamshell grind peels the ingredient apart as it is being cut, creating a very fine surface on cut ingredients.
