Additional Information:  A lightly used set of Tsuki-Ichihiro(月市弘) chisels, in good condition; the 30mm and 18mm sizes are unused. This set was sourced from the collection of a retired carpenter in the Tokyo area.

I have performed sharpening: the bevels are sharpened to 1000 grit, and the ura (backs) have been sharpened to approximately 5000 grit.
