I bought a R Sorby back saw with 3 1/2 inches under the back for larger tenon work. I was wondering if anyone can tell me a bit more about the saw or direct me to a site that can. I really looking for the age and history of this line of saws. A lot of Disston info but to much on others. I have made a couple of test cuts it seems to follow a line very well with no binding. The pitting in the tooth line does worry me a bit but what do I know LOL
