I still don't see what's so scary about it. Ok, you don't see anything in the back, but you're dealing with a very workable surface. As long as you don't rush the shave, it's all good. I'd do it myself just to prove it, but I reached the age where a full head of hair is a badge of honor as quite a few of my buddies are already balding lol.

One tip: Try to steal one of Josh's blades as big wedges have longest lasting edges. That reduces the amount of honing and stropping.
