Yoshimi Kato – Petty 150mm AS Kurouchi


Yoshimi Kato

Yoshimi Kato apprenticed at Kanehiro Hamono and then apprenticed under the guidance of Hiroshi-San (his Father in Law) who has also taught great blacksmiths like Yu Kurosaki. Yoshimi Kato strives to continuously improve his skills day by day working from Takefu knife village. Unusual for a blacksmith, Kato-San does not favor a particular steel. He is skilled with all steels that he uses. He believes that heat treating is where you should pay the most attention.

These blades are hand forged with Aogami Super. This steel is really easy to sharpen, takes a brilliant edge, cuts like silk and is super rugged for its hardness.  They are then clad in softer stainless steel to help with any maintenance issues.

Aogami Super ( Blue Super Steel ) is an improved version of Blue # 1. For Blue Super (Aogami Super or AS) they add more carbon for hardness. Te extra Vanadium gives extra toughness and creates smaller carbides. Blue Super is often considered by blacksmiths, to be the best carbon steel for knife making in Japan.


This knife is used for smaller jobs that are done on a cutting board. Perfect for slicing shallots, garlic, cutting herbs, and boning smaller proteins. Additionally, Petty knives are an indispensable tool for those who feel uncomfortable wielding a larger chef knife.

Care Instructions:

  • Wash and dry the blade by hand immediately after use. Dishwashers are very bad for all knives.
  • Use a soft cloth to wash the blade. Avoid abrasive dish scrubbers and powders as these can damage the finish of your beautiful knife.
  • Do not cut through bones. You can certainly cut along/beside bones, but do not cut into bones. This can, at worst, chip the blade.
  • Never use this knife to cut frozen food. I’m sure you have a 4×4 somewhere in your kitchen for this job.
  • Never twist or cleave the blade.
  • Always use a wooden or plastic cutting board. Never cut on bamboo, glass, marble, slate, a plate, china, marble, arborite or anything harder than steel.
  • Store knives in a way that the blades will not knock into each other.
  • Never transport knives unprotected.
