The takohiki knife typically has a long, thin, and single bevel blade that is sharpened on one side only. This design allows for precise cuts with minimal tearing of the delicate fish flesh. The length of the blade can range from 24 to 36 centimeters (9 to 14 inches), and the blade is often wider than that of a yanagiba knife, giving it a better surface area for the fish to adhere to.
