Martin. I did the same thing, with my first pocket knife in third grade. A beautiful Case XX, stag handled, Russ Lock. I really liked that knife. I was trying to shut it on the back of my pant leg like I saw my grandpa do. I forgot to move my fingers, when I saw what I done did I pulled the half closed knife off my fingers. The surgeon told my momma that's most likely when I seperated the tip of my pointy finger from my hand. They actually sowed it back on and it works well enough. I fake it and pretend I have feeling in it if someone's watching.
