Just in case you aren’t sure….

I do these things so you don’t have to experiment on yourself……

11,000 rpm 4 inch grinder (without the safety guard, of course…because I’m a guy) with an 80 grit flap disc…
skin on knuckle
0.0000004 seconds of contact time.

Skin gone.

But it is clean and should heal rapidly.


Now you know, just in case you were wondering.
