Yesterday I passed a barbershop and saw ads on their wall outside of men with beards and short hair. It is a revival or saving electricity ?
Razors are expensive,
They don't have to be! Dual edge safety razor blades are like $10 for 100. You could splurge ($50 for a nice one, or hundreds for a really nice, probably unnecessarily expensive one) on a nice handle that will last you the rest of your life, or get just about as good a shave with one that costs $10. Heck, if you're lucky you could find some old, nice one at a garage sale that's already been around 70 years, and will easily still be working fine when you're dead. Unfortunately, like just about everything else old and good, they've become a bit trendy, so it might be hard to find deals like you used to be able to.
