Zen and the Art of Food: Chopping Onions the Right-way

no idea what kind of kniffe this is

UsubaKnife

The Usuba knife, or usuba bocho, is the heavier, professional chef’s version of a nakiri knife. It is virtually the same as a nakiri except the edge of the blade is only ground on one side. For right-handed chefs, the grind – the sharpened end of the knife where the blade begins to narrow, should be on the right side, and for a left-handed chef it should be on the left side. This allows the chef to create thinner slices than with a nakiri knife, and with less ease than the nakiri knife offers.

“Usuba” literally means "thin blade" indicating its relative thinness compared to other knives, required for cutting through firm vegetables without cracking them.

Nakiri bōchō (translation: knife for cutting grees)

NakiriKnife

Nakiri Japanese knife meant for slicing vegetables. It has a light, thin blade that is ideal for cutting delicate produce. This knife’s blade is straight so that long cuts can be made without having to move back and forth. The edge of the blade is not traditionaly "hallow ground" for easy sharpening but it does help to maintain a razor sharp edge. Nakiri knives in the style of Tokyo are rectangular, while Nakiri knives from Osaka have a curved blade.
