Yeah, I had an OTF knife that I accidentally activated while I was scratching my chin with it. The blade came out with such force it pinned my tounge to the roof of my mouth! All could think of on the way to the hospital was how tis situation was just like when I bit into a BLT and ha forotten to remove the toothpick. Upon removing it the doctor was so impressed by the wickedness of the knife, he told me he would comp the medical treatment if hecould use it for surgery that night. I agreed. When it came time to return it in the morning, he refused. He baracaded himself in an air duct. SWAT was called. When they went to look fo him they found he had tunneled out of the hospital with my knife! How? He extended and retracted th blade thousands of time to in effect "jack hammer" his way through the concrete! All that he left behind was rubble and his initials in a boulder a mile away from the hospital.
