If I may, FME, when going at one heavily, burrs form at the edge. I strop them a lot along the way on a stiff Illinois fabric to knock it off. Sometimes you must breadboard the thing on something, Begin anew. My favorite is a glass bottle. Some use the side of a hone (guilty).
Killing it and bringing it back, as Glen refers to, makes you positively aware of where you are.
JMHO
Otherwise, the thing rears it's head along the way.
