Appears unused. Top of the line Disston offering in pristine condition. This and the other Disston also listed today both came from a 'never messed with' ca 1900 tool chest found in San Francisco which hasn't been touched in 100+ years. Straight, sharp and with set. 26" blade stamped '5' was the coarsest and largest size of the No. 12 sold at the time. Straight-back, deep ship pattern rip saw with an applewood handle. CA 1900-1915. 100% untouched and will glow with a gentle cleaning. Pictures don't do it justice!
