I find it easy to polish off the edges of the resulting Rockwell
testing dimple using a stone like you use to sharpen a knife. You can
eliminate the little dimple edges without much damage to the
surrounding area and completely refinishing the face of the lifter is
not necessary.
I've also never had a failure problem with any lifter hardness above
53, but the harder the better.
