Was never a fan of this method. Always just been particular on my skinning. Good skinning= little hair on the meat. Burnt hair on your deer meat, never seemed to appetizing to me.
Many guys own a knife, not as many do nice work with one. I cringe when I see someone cut across hair and into hide from the fur side, makes a huge mess, good thing there is fire for some of the skin jobs I see, lol. Seriously though, I keep a 5 gallon bucket with couple gallons of warm water in handy to keep my hands and knife cleaned up, it's easy to keep clean if you stay clean. I'm pretty fussy how I skin, I have done a lot of deer and have a system, between hunting at home and camp I am usually the guy who skins the deer for everyone else. I also think that having trapped and put up all my own fur since I was 9 years old with a father who made me skin, flesh and stretch every hide I took made a difference too.
I also get that most guys just want the hide off and hair gone, so keep rollin!!
Sadly most of my life has been wasted, but the rest I spent hunting, fishing, and trapping...
