At one time I was a professional woodworker, and I have made or built something in most categories from 50′ boats to small custom boxes. I have done some rough work like building bent wood fencing, some timber framing and house construction.
Back in the day I would sharpen all of my saws using the same methods shown on vintagesaws. I still have my saw sets. (& most of my other tools). I have a saw set for large 2 man saws and instruction how to shape and set the rakers somewhere.
