my dog can attest to the sharpness of the death traps. i had just caught a squeaker, got it to the boat, i had safely removed the hooks from the fish and releasing back into the water, when my dog starts yelping. He somehow managed to get the front treble caught just behind his front leg, and the rear treble just in front of the back leg. I have to admit watching my dog try to walk sideways was pretty funny. It turned out to be a shortened fishing trip and an expensive vet bill.
