Aron Ralston. A random hiker guy got his arm stuck when a boulder fell on him. He chipped at the rock with his cheap utility knife for 5 days, gave up on that, broke his arm, and proceeded to cut it off with his (beaten from chipping at a rock for 5 days) dull $5 Utility knife and some pliers. He then went on to climb down the 65ft mountain and walked into some peoples house and ate oreos. HE CHOPPED HIS FRIGGIN ARM OFF WITH A DULL, RUST, BENT KNIFE AND PLIERS... AND ATE OREOS SHORTLY AFTER. I don't think YOU'D be eating oreos after that. Nope. You wouldn't.
