This is a convenient saw, much sharper than folding saws, etc., and is a traditional double-edged saw (coarse and fine teeth) with a total length of 57 cm. The official name is "Betsu-chou (Custom-Made) Sho-mei (Authentic) Touroku (Registered) Dai-Gokujou (Supreme Quality) Hon-me-date (Hand-Sharpened) Getsusei-saku (Moon Star Made) Ryouba Noko (Double-Edged Saw)". The blade length is 24 cm. I purchased this item in a technology and home economics class in junior high school, and although it shows signs of use, it still cuts well. My last name is written on the cover with a permanent marker. It's a relatively uncommon name, so I haven't included it in the photos. It should come off with thinner, etc.
