Damn---anybody remember that guy that cut his leg(I think it was his leg)off using a pocket knife? He was out logging or something, and a tree fell on him. After he cut his leg off, he crawled to his car/truck/whatever and finally was able to call someone for help.
edit: found story about it:
<< In the summer of 1993, traumatic dissociation saved Donald Wyman's life. While working in a remote Pennsylvania area clearing timber, Wyman suffered a terrible accident. A huge tree fell on him, pinning his left leg. He screamed for help for an hour, all the while trying in vain to dig his leg out from under the huge tree. Then Wyman made a decision. Because of the seriousness of his injuries and the remoteness of the area, he knew that he would die before anyone found him. So he made a tourniquet from a rawhide bootlace and used his chainsaw wrench to tighten it. Then, using a pocket knife, he set about methodically cutting off his left leg about six inches below the knee. When he'd severed the leg, he crawled to a bulldozer 500 feet away, drove it about 2,000 feet to his pickup truck, then drove the truck about two miles to a farmhouse. The farmer, who called paramedics, described Wyman as "sharp and mentally strong" >>
