Boshu Saw, Nakaya Yoshizo, 240mm (8 sun), Ryoba (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. [There is some minor rust. Please check the images.] Thank you.
