Looks painful
Power tools, though incredibly fun to use, are not playthings. As you saw earlier, even if you’re careful, things can go wrong in a blink of an eye. In this person’s case, it did, and two very long nails shot out of a nailgun had penetrated him in the knee.
The x-ray shows just how lucky the man was, despite becoming a cushion for construction nails. The two metal fasteners had somehow navigated their ways into the narrow opening between his femur bone and kneecap. Sure, flesh and cartilage took the hit, but at least he wouldn’t need to get his bones fixed up.
