Additional Information: Used, they came from a retired carpenter in Tokyo. I sharpened the bevel to 400 grit, and the Ura to about 6000 grit. The rust is quite serious, but it does not affect the basic functions. 

 I felt that they were similar to the style of the second generation Hisasaku when I  got them, but better made than the second generation Hisasaku. I asked Mr. Tsuchida Nobou for his opinion. He thought it was the work of one of Hidari Hisahiro's disciples. But it is not possible to determine who it is, and no relevant information can be found on the mark. Also, the kuchigane is handmade.

Please install the chisel into the wooden handle according to the position shown in the third picture.
