I round the front . I have the holes drilled in both sides of the bolsters and a 1/8" rod rivets thru both of them and clamp them together with vice grips and scribe a line about .100 down from the top on each side and just grind them round . and look at them often to see that each side is the same . All eye ball ..
I don't have a top view of it , I'm putting bolsters on a knife tomorrow I'll take pictures . but this is all I have right now .
