I meant to post this tip on earlier in the season but it hasn't happened to me in awhile.
Occasionally when I have a really tough tail to pull the entire bone pulls off the hide. I used to struggle with them using a tail stripper and a pair of pliers until someone showed me this. I attached an underwater beaver snare with an Adams lock to my wall where I'm skinning. That way it only takes me a few seconds to secure the tail bone, attach the tail stripper and lean back and strip the tail. Just a little tip to make life easier.
