Have a great thumb pic that will put that smash to shame, no way to post it. Double whammy. 5 weeks ago a pit attacked my Aussie, 4 of us were trying to pry him off without ripping the skin off the side of my dog's face. My thumb got in the mix and his jaw smashed the **** out of the end of it above the cuticle but below the joint. Swelled up, drilled nail for pressure, good to go. It finally fell off last Sunday, Monday night I'm rebuilding gayzr axles, putting an outer cv back on the shaft, it is being stubborn. I hold the cv, helper is hitting the cv to get it on the shaft. He 2 hand above the head swings and misses, hits my ****ing thumb right where the nail should be and up on the joint. My new little baby nail that was trying to grow is blown in half. My list of people I trust with a hammer just got shorter.
I've also smashed the end of this one off in a press brake in '15 and its the only bone in my body I've ever broke in 99. Dominant hand thumb. Very important for wiping you ass, hitting the space bar, jacking off, picking stuff up etc.
