This saw came from a collection of saw with several saws sharpened by Tom Law. You can see the black marks on the tooth line where he sprayed gun sight, which he used when he sharpened saws. I did some test cuts and it cuts great.
This saw also appears to have a spine the was made by a previous owner. It is two pieces of steel pinned together. It's very well done and saw is straight and cuts very well. The blade is 26" long with a depth of cut about 2 1/2".
