I am just starting to hand push and am trying to get my graver sharpening skills right so the graver will cut not stop.I was wondering if all engravers including the knife graver, round graver, and flat graver should all have heels on the bottom of the graver. In watching Sam's sharpening videos I only see him putting 15 degrees on right and left side. I did this with my #4 flat and find a lot of resistance
