Additional Information:  Unused, in good condition. I purchased it from a tool collector. 

According to information I recently gathered from the web and Mr. Tsuchida, these blades were forged by the late Hisashi Natsumiya, a renowned blacksmith from Kiryu, Gunma Prefecture, who specialized in Mini planes (Mame-ganna).

He did not operate under his own brand; instead, he primarily produced blades for the ‘Kunihide’ and ‘Yoshihiro’ brands. It is said that his techniques also had a significant influence on the Metsugi blacksmiths.

The 4, 5, and 6 blades (Kunihide brand) are the smallest plane blades I have ever seen.
