Steel, Is the skin shredding on you or just sticking on there? Have you ever skinned a catfish? We would take pliers and peel the skin on them like that.
How are you trying to skin it? Do you have it tied up by the head so you can work down? Have you tried using a surgical scalpel, it would be tedious but certainly it would come off.
If you were trying to save the head skin you could lay it out, cut the skin off the head, then tie it up and work down. Thats about the only way I know how to do it but that was from watching someone else and it was not a python.
I will call the guy I know and let you know what he says about it, Interesting subject though.
