Additional Information:  Lightly used, in good condition. I recently bought it from a carpenter in Tokyo. The chisel set has 36mm and 42mm chisels of Mentori style, and the rest are Kakuuchi style. 

Judging from the features of this set of chisels, the original seller of this set of chisels should be Tsuchida store. But unfortunately the handle of the chisel is not original. 

Since the narrowest 3mm chisels are more easily worn out with use and sharpening, 3mm are usually made longer in the chisel sets sold in Tsuchida shops.

The "line" in the last picture is the burr I created when sharpening them. The fact that it can be completely removed from the tip of the blade shows that the microstructure of the chisel steel is very uniform and has almost no impurities.
