This has probably been covered before, but I wanted to spread the knowledge. Today, I discovered the magic that is back filing. So first, I made sure that I filed away as much of the sidewall as possible, using a sidewall remover. Then, I took a coarse (100 grit) diamond stone and put it in a multi-tuner set at 5 degrees. I then started grinding my side edge (back and forth until it felt smooth). I then took my file, put it on a three degree side edge guide, and proceeded to set my side edge. The file cut a lot smoother than it normally does, since I was working with an edge that had been over-beveled. I then continued with a progression of diamond stones, all at 3 degrees.
I found that I was able to create a much sharper edge using this method. And I wanted to share it with those who may not have known about this before.
So basically, I have discovered that the keys to sharp edges are 1) making sure you file away as much of the side wall as possible and 2) back filing
