"Sharpening Western Saws"
Brit01425 posted a two hour video on youtube called “Sharpening Western Saws”. Its crazy long, but worth every second. It is what really cemented my understanding of the theory. I looked over it several times because of the length, but never regreted taking the time to watch it when I was done! He files a saw flat and recuts the teeth, and explains at length in true Brit style. Check it out.
