Are you extending Friday Dewey?

Rule of thumb number 2 is always keep all body parts towards the bunt end of
sharp instruments

Rule of thumb number 3 is that it does not hurt so much if you pick up a
soldering iron by the handle..............8-)

As a rule, I never place my thumbs where they can be hit with a hammer.
That's a technical dropping.

Dear collegues,

I have heard of a thumb rule, never place them along and close to the
edge. Hence, we place them (when suitable) in the center. I have
forgotten why this rule. Was it because of vibration nodes, warpage
during soldering, tempcycle issues or what? Is there a IPC standard or
other reference?
