Boshu Saw, Nakaya Yoshizo, 300mm (1 shaku 1 sun), double-edged saw. Unfortunately, the maker closed down several years ago. I have been using this saw since I was a young apprentice. Difficult to obtain. There is little rust, and the condition is good. There will be no further stock or listings. This is the last one. Thank you.
