As I mentioned a few posts back, I can't see why waxing wouldn't still be a reasonable option. Doesn't take much to mix up a batch of "special blend", slap it on and rip it off. Has to be easier than sourcing suitable metal, cutting it down to size and sharpening it up.
Sure, it hurts like a bitch, but as indicated it lasts much longer. I knew a number of soliders who'd wax their faces before going bush to avoid the need to shave in the field.
