It was a Sunday morning and I went to run the line before church. Had been eyeballing a little ditch creek for beaver/otter and had the time to set it after checking my other traps. Took a Duke 330 down into the ditch and found some sign. I set the trap as I always did, and put it in place upside down as I normally do. The safeties fell off when I was putting it in place. Not a problem, happens all the time when I use the dukes. Not sure why or what happened, but I was removing my hand from the top of the trap and it lunged at me. It made good contact with my right hand and caught me about where the thumb meets the wrist. Of course I didnt happen to bring my setters or emergency rope. In the 5 seconds it was on me I think I saw my life flash before my eyes. I quickly wondered if I was going to have to drive home with this piece of metal on my arm or if I would just lay down in the creek and let nature take me. I am not really sure how I got it off as it happened really quickly. As best as I can remember I shoved the springs into the bank, put my knees on them to compress them some, and pulled my hand as hard as I could. Took a week or two to get back to full function, but other than that I was ok. I definitely recommend carrying some rope just in case you get in a bad spot. I also never stake mine until the set is made.
