Hi Chris
Having said that the only serious damage I've done to myself with a
power tool was with an angle grinder. Sheer carelessness and nearly
any other sort of tool would have done *far* more damage, as it was
the basic bluntness of an angle grinder wheel meant that I just lost a
bit of thumb.

Mate of mine told me once why 9" angle grinders have two handles. Not so
much so you can hold on, more so you know where both hands are all the time.
I've used this advice (don't let go with either hand till blade stops) ever
since a minor mishap - let the grinder drop to my side where the blade
became tangled in my jogging bottoms, pulled it into my leg whilst still
moving a bit.

Fortunately the joggers slowed it down enough and it only left a scratch on
my leg. Full whack and it would probably have taken it off.
