I just received a Disston D100 from a recent Martin auction. Saw was described as "unused", and looks pretty much unused, for a 50 year old saw. It is a short saw (can't recall length) and 10 point. Did not feel very sharp for an unused saw, however when I did a test cut on a piece of poplar, it cut like a hot knife through butter.

I'm into the saw just under $100.00 (total for shipping and everything), for a mint D100. I'm happy!
