We also went to visit another one of our Syoushin sharpeners: Norikatsu Nishimura , who is also a Dentou Kougeishi (Traditional Skilled Craftsman, 伝統工芸士).

When we arrive, we saw Mr. Nishimura sharpening our kiritsuke shaped gyuto.

After the polishing wheels, hand polishing is required to bring out the cladding and the shinogi line.

There is an extra step for our gyuto: hand sharpening on a natural stone, which means you will receive a gyuto with an sharp edge OOTB :D

We checked out the edge by cutting a string of hair (without any backing, just holding the hair in the air and chop), the result? We were satisfied :)
