We owe it to King Camp Gillette for making it easy to be a well-groomed gentleman without cutting your head off, or having to visit the barber.
He was a clever tinkerer and, apparently, an equally good marketer of his "safety razor."
Since his invention, razors have seen many modifications to Gillette's basic idea - not to mention electric razors (do any guys use those anymore?).
When the Gillette products got too expensive for my taste, and I couldn't keep track of each new type of razor and the costly blades that went with them, I opted for buying cheap disposable razors in bulk. The one pictured is $10.49 for 100.
Depending on your testosterone level, one is good for a week - at least. Longer if you can put up with minor discomfort.
Added benefit: No problem if a daughter borrows your razor. Who cares?
