No matter what brand or kind of razor you use, it uses the same metal blades as every other one on the market. Except for the Skarp Laser Razor, that is. This revolutionary grooming product uses a laser that targets a specific chromophore in hair that allows it to cut it cleanly, emitting light only when contact is detected. As a result, it never needs a blade replacement, and doesn’t even require any water — although you can still use it in the shower if you want. Powered by a single AAA battery, it’s available in aluminum with a silver or black finish.
