Somewhere in this thread one of the authors talked about sharpening plane blades. For an interesting technique look up Rob Cosman’s videos using Shapton glass stones to sharpen. Finally, if there is any interest I will post a picture of Shapton stone holders that I had a local plastic fabricator make for me based on my understanding of WE stone geometry.
What I am not so sure about is how close to a certain angle setting does one have to get to sharpen nearly perfectly and how quickly can one sharpen a blade to near perfection. Too bad there is variation in WE stone geometry.
