Congrats on the doe Badger.

I have a suggestion for anyone who has to finish a deer with a knife. DON'T go for the throat! It is far too hard to hit the carotid artery because it is protected pretty well by the spine. If too easy to get injured while the deer freaks out as you try to get the knife all the way in to the artery. Instead, simply stab quickly once on each side of the ribs and get the same effect as a double lung shot. (in your case, you simply needed to get the one ontouched lung) The lungs quickly collapse and the deer expires in less than 60 seconds. Much safer and cleaner than digging the knife around the throat for that artery.
