it sounds like a specification for the classic D8 Disston rip saw. If you are going to copy any rip saw then this is probably going to be top of the list. Incidentaly they did offer one with a plastic handle in the 1940`s i believe!!!! It begs the question as to if it is possible/legal to copy this?, and why hasn`t someone done it already? and do we stop at rip saws or start talking about cross cuts too?? Again a replica of the D8?? Ideally the CF could be involved with distributing them in the Uk.
Also the Axminster tool catalogue offers a 4.5tpi rip saw 26''long ,taper ground,nickel chrome steel with breasted tooth line and solid walnut handle for £57.39 has anybody tried one of these?
