the solution is simple
Grow a beard!
Ive not always had a beard, and I still really cant grow one but I still do not shave. Google the words growing a beard and you will find many pages dedicated to the reasons why a man should allow his hair to grow. I myself stopped shaving because I believe a human male/fenale should look like he/she was designed to look like. I know this is unrelated talk but its worth a consideration. I mean who really shaves in the backcountry? but if you must, why not cut down a single blade disposableor even if u want to carry the mach 3 cut down the handle on that, either that or fashion one out of a few popsicle sticks.
