Yanagiba / Sashimi Knife

A Yanagiba knife is a knife used for making sashimi. To cut sashimi cleanly, it must be sliced in one direction, which is why the blade is long and sharp. In the Kansai region, it is sometimes called Shobu or Masao because its shape resembles the leaf of an iris.
Nowadays, the Yanagiba knife is almost exclusively used for slicing sashimi. It is so popular that when people refer to a "sashimi knife," they are generally talking about the Yanagiba knife.

The blade length of a yanagiba knife is the length measured from the tip to the edge of the blade.
The blade length is selected based on the ingredients to be prepared, the size of the cutting board, and the kitchen space.
