Years ago, I shot a small buck, nubbins, with my bow. After about 3 hours of trailing, we finally found it and it was still alive and trying to get up. We sat for another 15 minutes and decided I would take my knife and finish the job. It wasn't moving very much at this point and getting weaker so I just wanted to put it out of its misery. The guy with me put a big branch on the back legs so it wouldn't be able to do anything there, I got up behind it, stepped on an ear and slit the throat, it only took about 15 seconds to be done with. Would I do it again ??? I don't know, the conditions need to be just right.
