I found this on YouTube a while back & watched the full 2 hours & 15 minutes. I found this very helpful, started sharpening my two saws immediately, and they work quite well yet today.
I also used this information when I re-toothed a cheap big box store dovetail saw that was crap, and now use it in my homemade kerfing saw - https://www.lumberjocks.com/showcase/kerfing-plane.82673/
Thanks for sharing.
