The Sujihiki Knife

The Sushikiri knife is a long sharp blade specifically built for slicing. The sharpness and length of the blade on a sushikiri (similar to Yanagabi) allows it's holder to slice through a large piece of fish or steak in a single motion.

As said by a famous Japanese lady "The final stroke of a dish should be the same as the movement of a bow over a violin in an orchestra - one smooth movement." This prevents damage and ensures smooth clean finish on the fish (or whatever else you are cutting).

The sushikiri is a double sided knife which is easier and more versatile than a Yanagiba (single beveled) so unless you are Yanagiba obsessed it it most likely the knife for you to finalize your dish as beautiful as when you begun.
