Tying stiff hinge sections at home one night a few years back pulling it all down tight and the hook slipped off the puller tool and drove the size 5 choddy hook straight passed the barb and under the nail couldn't get the bugger out after ten minutes of swearing and pulling with pliers off to A & E.

Removing eyes from a rod, to re-ring them, i used a bit too much force and the foot of the eye disappeared in a finger only to be stopped by the bone. Sissy that i am, i fainted, but my dad caught me on my way down Was really nasty.

Fishing in france on some lake with boulders and huge stones, landing a fish was a bit of a challenge. So on the way back up i slipped, and cracked some ribs because fish before your own health. Hands up with the net, so ribcage fully exposed. I had another 2 weeks to fish, also pretty nasty with those ribs, but the fish was ok:P

And i suffered some injuries to the ego, but that's fishing
