I had surgury on my dominant arm once and found that with very little practice you can become ambidextrous. I would take it slow and give it a try with my HB. If bloody mess results then it would be on to the electric razor.
I would just put the headblade on my big toe and shave my head that way! LOLReally I dont know what I would do, unless I go and buy one of those skin caps that make you look bald and wear it like Warhawk does. Yulp thats right folks....under that skin head of warhawks ..HE HAS A FULL HEAD OF HAIR! LOL
There are some things a guy ought to think about practicing now... before you loose the use of your dominant hand or arm.I'm not going to be graphic but the day after my rotator cuff surgery (dominant side) I discovered that I was very un-coordinated with my left hand in reaching a certain unseen place! I really can't imagine putting a deadly weapon in my left hand and trying NOT to scalp myself!
