And as Allan Quatermain said to Tom Sawyer, "take your time, you've got
all the time in the world".

Thank you for sharing both of your lessons that you "learned the hardway"--I
was ignorant of
both issues and was likely to repeat them--especially the one about "relying
on hand pressure
against a fence". Secondly, in view of all the accolades given to carbide, I
did not consider it's
brittleness--clearly a factor here! If there's a lesson here, it's got to
be "don't take too much for
granted!"
