I like angle grinders. Of all the whirling abrasive machines out
there, they're far safer than most of the others.

Although they frighten the life out of me, they are safer than a lot of kit.
I got attacked in the leg by a (slowing down) diamond disc on a 9" grinder.
It caused a fairly deep abrasion but didn't cause a cut, No bleeding at
all - although I still have the scar from 2 years ago.

Certainly a lot less hazardous than a circular, band or chain saw when
it comes to exposure to a moving blade. Although a big grinder is
likely to kick if not used carefully I've never done more than scuff the
toe of a safety boot with one.
