Long and Narrower blade is suitable for slicing tasks. Especially for preparing fresh, good&beautiful shape of raw fishes (sashimi).


The takobiki is a variation of the yanagi and is used to slice straight-cut sashimi. It’s thin body makes cutting thin slices of fish easier than the yanagi. The blunt tip and balanced weight works well on difficult ingredients such as octopus, from which it gets its name. Originated in Kanto (Tokyo) region.


The Usuba has a thin & straight blade for clean cutting on the chopping board;
paper-thin slices are no problem, even with ripe tomatoes.


Deba are Japanese style kitchen carvers primarily used to cut fish, though also used when cutting meat. Its thickness, and obtuse angle on the back of the heel allows the user to cut off the heads of fish without damaging the body. The rest of the blade is then used to ride against the fish bones, separating the fillet.
