Nakiri is a Japanese term, meaning “greens cutter.” In the olden days of Japan, this knife was commonly found in household kitchens. To this day, it’s still held in high regard, especially by professionals.
The most striking feature of the nakiri is its rectangular profile, which of course has a function. The flat edge is suitable for repetitive chopping motions that will make full, parallel contact with the cutting board, providing a clean and consistent cutting rhythm as you work through those greens.
If your goal is to cut vegetables specifically, a nakiri is the more effective option. For the same reason you might buy running shoes if you plan on doing a lot of running, buying the right knife for the right cutting goal in mind will help you work more effectively.
