Do you use a new disposable razor every couple of weeks? Billions of plastic razors are tossed into landfills each year. Razor blades eventually rust away, but the plastic casings hang around a lot longer. The best environmental choice is an all-metal safety razor, which is 100% recyclable. I’m happy with a replaceable cartridge and reusable handle, which I’ve had for years. Apparently most men in the US already use reusable razors, but not women. What’s up with that?
