as the awl spreads the wire to each size hole, move it to the next... you are probably wondering why not just have one hole.... well, you need a progrssion of holes , if the hole is too big, you end up driving the wire into it with out spreading it, if the hole is too small, the awl cant sperad the wire... hence the progression of holes...
when you finish, sometimes the wire or lip will have marks or burrs, simply polish it with a piece of # 600 sand paper.. do it now!! or you will forget...
