Nakiri bocho

Nakiri bocho and usuba bocho are Japanese-style vegetable knives. They differ from the deba bocho 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. While the deba bocho is a heavy blade for easy cutting through thin bones, the blade is not suitable for chopping vegetables, as the thicker blade can break the vegetable slice. The nakiri bocho and the usuba bocho have much thinner blades, and are used for cutting vegetables. Nakiri bocho are knives for home use, and usually have a black blade. The shape of the nakiri bocho differs according to the region of origin, with knives in the Tokyo area being rectangular in shape, whereas the knives in the Osaka area have a rounded corner on the far blunt side. The cutting edge is angled from both sides, called ryoba in Japanese. This makes it easier to cut straight slices. Usuba bocho are vegetable knives used by professionals. They differ from the Nakiri bocho in the shape of the cutting edge. While the nakiri bocho is sharpened from both sides, the usuba bocho is sharpened only from one side, a style known as kataba in Japanese. The highest quality kataba blades even have a slight depression on the flat side. This kataba style edge gives better cuts and allows for the cutting of thinner slices than the ryoba used for nakiri bocho, but requires more skill to use. The sharpened side is usually the right side for a right hand use of the knife, but knives sharpened on the left side are also available for left hand use. The usuba bocho is also slightly heavier than a nakiri bocho, although still much lighter than a deba bocho. Deba bocho (, literally: pointed carving knife) are Japanese style kitchen carvers primarily used to cut fish, though also used when cutting meat. They come i different sizes, sometimes up to 30 cm (12 inches) in length. The deba bocho first appeared during the Edo period in Sakai. It is designed to behead and fillet fish. Its thickness, and often a more obtuse angle on the back of the heel allow it to cut off the heads of fish without damage. The rest of the blade is then used to ride against the fish bones, separating the fillet. The deba is not intended for chopping large diameter bones. Usuba knives () are the traditional vegetable knife for the professional Japanese chef. Like other Japanese professional knives, usuba are chisel ground, and have a bevel on the front side, and have a hollow ground urasuki on the back side. Usuba characteristically have a flat edge, with little or no curve, and are tall, to allow knuckle clearance when chopping on a cutting board. Usuba literally means "thin blade" indicating its relative thinness compared to other knives, required for cutting through firm vegetables without cracking them. The Kanto variation have a square blunt tip, making it appear like a small meat cleaver. The Kansai, kamagata style variation has a spine that drops down to the edge at the tip, allowing the usuba to do fine delicate work. However, this tip is also delicate and can be broken easily. The usuba is particularly popular with Kyoto chefs, who use the Kamagata usuba for most of their work. Since Kyoto is landlocked, they rely more heavily on vegetables than Tokyo, making the usuba the quintessential knife of professional chefs there. In Kyoto cuisine, the versatile tip allows for intricate cuts and preparations, however due to its height and straight edge usuba in general are used for chopping vegetables, and specialized cuts such as katsuramuki, shaving a vegetable cylinder into a thin sheet.[1] The nakiri bocho are similarly made but sharpened from both sides. They are preferred for home use.
