I don’t change handles often, but I will add an actual bevel. I have rebeveled 2 of 3 of mine down to 5 to 6 degrees per side then add a secondary bevel. One I did with a belt sander the other with hand files. Both were very thin and had incredible cutting ability. One was a little too thin and took some damage so it had to be fixed. The other hit a rock and also has to be fixed.
