One of the hand saws that I bought from eBay was an old Disston rip cut saw. It arrived in pretty poor shape, but I hadn’t really paid anything for it, not much more than the postage really.
The teeth were all blunt and misshapen, and it was difficult to tell how many points per inch (ppi) it was. Needless to say, it couldn’t cut through a blancmange, let alone a piece of wood.
