My dad tanned the hide of the first buck I killed with my flintlock and I cut off a strip of leather from the neck and removed all the hair from it. I cut it into little pieces and I now use that leather between the flint and jaws on the lock of the gun I used to kill that buck. Nothing too 'big', but the smile is quite large when I'm sitting in the woods with that rifle, look down, and think about where that little piece of leather came from.
