I have a year old BP that wasn't handled much by previous owner. I warmed the end of a snake hook in my hand and started stroking his body with it gently to get him used to being touched for short periods, then moved on to holding him with gloves, then one glove, then none once he got used to contact with my skin.

Has worked quite well and is comfortable being held now.Worked a bit too well, He has gone from very timid to bloody stubborn, the little beggar pushes his body down so i can't get the hook underneath to lift him out sometimes now!!
