Last year, MB750 on my bare left hand across the joint at the base of my thumb and the joint at the base of my index finger. It hurt a lot, lucky I had a set of one hand setters with me.

Besides getting thumb and index finger in traps, getting bit by a gray fox

Thumb in a #3 Duke while cat trapping.

Both hands across the fingers in a brand new 280 Bridger magnum. At the time I was used to settings the springs with setters and then squeezing the jaws together by hand to set the trigger (I now use setters for this ;)). Those first gen Bridger magnums had the round rod safety hooks that were just a bit long, making for a tricky leverage curve when squeezing the jaws together. Anyway, I was in the process of doing so when the trap slipped, and it just so happened both the safety hooks jumped off. Fortunately I hadn't anchored the trap yet, and I had the thumb and first finger of one hand free so I was able to start and drive about a mile to the farmers house on the property I was trapping and he, with help of another local farmer who happened to be there were able to remove the trap.
Honestly I wasn't aware of any pain until circulation started back in, and that passed only after several minutes of vigorous dancing, in which I must say I invented some pretty creative moves. All in all I escaped with only minor bruising, and a lesson well learned. On the bright side, it gave the local farmers something to chew on for awhile. I can only imagine what their version of the story might have been...

This past summer I was trying to catch the third and last beaver on a private pond. The 330s weren't connecting so I pulled out my Hancock and set a dam break. Two nights of debris and still set, I had the trap open and safety on. I tried to adjust the trigger and at some point the safety came off. Next thing I know, I was on my butt with a welt on my forehead. Man, those things close quick. I reset the trap and had the beaver the next morning.

when i was young , in high school , had a friend trapping with me , he went down stream to a dam i went up stream to a dam , in winter , I made my sets an came back to truck, and waited , no friend , so i honk the horn , no friend , so I started to go see what was wrong , THATS went I see him coming out with both hand in a 330 , seem he had every thing ready to go thru the ice when he notice a branch in hole , so he set down 330 on ice , got the branch out , and reach back for the 330 ,that was laying on ice and it went off ,jump up and got both hands , he had to unwire 330 from poles ,

Last year I tore my rotor cuff pulling myself up onto a Creek bank.

Completely blown rotator cuff muscle, not repairable debilitating injury. Carrying heavy drowning weight up a beaver pond bank in too big of a hurry, feet slipped out jarring the shoulder.

Still hurts !

Thumb in a 220 Belisle, same thumb in a 220 Victor, thumb in a #4 coil, and thumb in a 1 1'2 coil which hit just so on the nail to have it hurt almost as bad as the other thumb incidents. Neither thumb looks completely normal any more.

I had a 14 go off and the tooth went through the thumbnail.
