Additional Information: Used. Although there is rust on the blade's "ura," the blade's steel is relatively thick, so it doesn't affect its practicality.

Since there are many fake Kunihiro pieces, I asked Mr. Tsuchida Noboru to authenticate this blade and he confirmed it to be authentic.

Unlike the common blades nowadays, it is thinner. Please refer to my blog to learn more about this change.—— 「The evolution of the Japanese plane blade "Nikuoki" since the end of the Edo period」
