I don't think this counts as "other than a razor," but it would certainly be included under Letterman's "Stupid Human Tricks" category.
More than 20 years ago, curious to see what a "straight razor" might feel like against my skin, I snipped the guard off of a single blade disposable razor. As I mentioned in my introductory post, I will leave the results of my stupidity to your imagination. *sigh*
Namaste,
