The "Sujihiki" Knife | Carving Knife | "Muscle Cutter"

Our 'Sujihiki' is a real statement in the kitchen or at the table. Made from high carbon Japanese steel from Aichi, it has a tough edge for slicing, and perfect if you want a knife that will remain sharp for a very long time.

PLEASE NOTE - For better or worse every handle is different. The images of handles change from knife to knife - the burl of wood is like the daily weather - hard to predict. 


Blade Length: 260mm (10.23") | Over All Length: 370mm (14.56") | Blade Thickness: 2.8mm (0.11") | Weight: 215g (7.58oz) | HRC: 58-60

High carbon AUS10 67 layer Damascus Japanese steel. 

The Sujihiki knife is a long sharp blade specifically built for slicing. The sharpness and length of the blade on a Sujihiki (similar to Yanagiba) allows its 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 a smooth clean finish on the fish (or whatever else you are cutting).

The Sujihiki is a double-sided knife that is easier and more versatile than a Yanagiba (single bevelled) so unless you are Yanagiba-obsessed, it is most likely the knife for you to finalise your dish as beautiful as when you began.
