I don't own a single knife that I haven't accidently cut myself with and I have a good size drawer full. Crazy thing is that I've started making them and I'm seem to cut myself more making them than using them. LOL
No big horror stories but when I was about 10 or so I was cutting apart some little plastic paint cups that came with some arts set I had. I slipped and laid my thumb wide open. Mom was asleep (worked nights at the time and I wasn't supposed to be dong what I was doing). I went into the bathroom and man did it hurt. I started shaking my hand, like you do when you smash a thumb. Didn't think about the fact that I was bleeding and proceeded to sling blood all over the bathroom. It was everywhere. Got it a bit of trouble for that one (for the mess, not for cutting myself).
My pappaw gave me my first pocket knife when I was 6, a Camillus scout knife which I still have and cherish greatly. It would shave. Pappaw's philosophy was simple, "He'll cut himself a few times but he'll learn how to handle it." Well, he was right. His obsession over a dull knife has rubbed off on me. Can't stand a dull knife.
