In pistols these days it's popular to "melt" the edges,taking off the sharp 90 degree edges by rounding them .Or you could chamfer them , that is cut a flat on the edge, 45 degrees to the side. Personally the chamfer looks better. I think blgoode means ease instead of east, but a chamfer is flat ( unless they changed that word too, no english in this country anymore) melting is round.
