However, if you shave, especially with a straight razor, you might catch interesting girls as well. Risk vs. Benefit?

(Kidding, I'm kidding. :-)

My guess is, any razor can nick the skin, and (in theory) open the door to microorganisms.

As I understand it, any outdoorsperson/gardener/survivor should be up to date with tetanus shots.

(I'm not getting on a soapbox; I just realized that I'm overdue. Got to get that dealt with SAP.)

EDIT: Just thought I'd add that, while camping, I once used Polysporin ointment to shave (using a safety razor). Smooth as silk. And fortuitous, perhaps, in zapping microscopic creatures.
