If that mink, ever gets hold of your hand, it wont be just a bite, he will slice it bit by bit like a tin opener!!, the pain i would imagine, would be severe!!
Fair play for trying to tame him, but i have a feeling, you might not get far, but i would be happy for you to proove me wrong.
Mink, are not like ferrets, they are wild mad feckers...lol
Good luck......
