IMO, there are two things that I believe are must haves that will help you make sure you are really creating a burr.
– A permanent marker to mark the entire edge (heel to tip). I personally like a red marker better than the traditional black color marker.
– A magnifying glass to make sure that you are fully removing the red marker. I have a
UltraOptix 7X Aspheric LED Lighted magnifier (same model that Tuffy uses).
