Single bevel knives are traditional Japanese knives. They have an omote, a shinogi and an urasuki. These knives are usually a little thicker at the spine and body than Japanese double bevels but are thinner right behind the edge.
While they leave a better surface finish, the produce must bend further because of the thickness of the blade. These are the knives of the established traditional Japanese cuisine and were originally developed from the Chinese double bevel knives. They are sharpened along the single bevel by applying pressure to both the shinogi and the edge. Honbazuke is the initial sharpening that forms a flat surface along the perimeter of the urasuki strengthening it.
This practice also straightens the backside and lays a shape for future sharpening. The omote is sharpened much more than the urasuki in order to maintain the function of the single bevel. Kansai style knives usually have pointed tip for vertical cuts, which helps in decorative tip work. Edo style knives have a square tip used for horizontal cuts, rendering a more robust working knife. The standard Japanese knife kit includes the yanagiba, deba, and usuba. They are essential to Washoku.
The most popular knife for cutting fish, also known as shobu-bocho. It is used to highlight different textures of fish in their techniques: hirazukuri to pull cut vertically, usuzukuri to pull cut thin vertically, and sogizukuri to pull cut at an angle. It is used to skin and sometimes scale and de-bone certain fish. Yanagiba have angled tips and are generally heavier and have less sloping. A regional variant, takohiki is lighter, thinner, flatter, and shorter in blade height than yanagiba to allow easier cutting through dense flesh such as that of an octopus. General size is 270 mm to 330 mm.
