Ouch! I have a scar on my forearm a couple inches above my wrist, so people think I am a cutter LOL.
Just like reloading, make sure your kids and signifcant others leave you alone when sharpening. My wife walked in and said hey honey, I turned and a few minutes later I realized my pants were covered in blood. It was a cheapie 420ss Gerber, and it opened me up deep and I didnt even feel it. Hair splitting sharp.
