Frequently Asked Questions about the Izutsuki Line
What is Yasugi Paper Steel?
Yasugi paper steel is a high-purity Japanese carbon steel, here in its blue variant at 66 HRC. It can be sharpened to a very keen edge and, thanks to its high hardness, holds that edge for an exceptionally long time (high edge retention); it is not stainless and requires care.
What are the differences between the steels of the Izutsuki line?
The Nakiri use blue Yasugi paper steel at 66 HRC, Nanbu Gyuto and Petit use a V2 special steel from Takefu with 25 layers of Damascus at 65 HRC. Both are very hard, retain their edge well, and are not stainless.
Who forges the Izutsuki line?
Toshiki Nanbu in the Echizen tradition in Fukui. The blades are hand-sharpened by Kazuyoshi Honda in Takefu.
How do I care for the Izutsuki line?
Wash by hand, dry immediately, and occasionally treat with mineral oil. The hard carbon steels are not stainless; with a little care, they will stay sharp for a long time.
Who is the Izutsuki line suitable for?
For experienced users and enthusiasts who are looking for maximum sharpness and hard, traditional carbon steels and are willing to accept the slightly more elaborate care.
