As for skin tears...
As truly weird as it may sound, the more you moisturize your hands (softening callouses), the less likely they are to tear. This is another trick I learned after getting into strongman. Tears happen, but they can be minimized by a great grip and soft hands. Tears happen as the bar starts to slip, and the friction between your skin and your body is less than the friction between you and the bar

This is why a super human grip is a bonus. Less bar slipping. Softening the hands using hand cream or whatever helps because callouses seem to be the weakest point in the hand. The place where the friction is most likely to be different, if you will.
