How is this thing called? (Men hair accessory)

There are dozens of razor thinners available on the market. My hair-stylist uses the razor thinner when my hair gets a bit too thick for just simple scissor cutting.

Frankly, I'd not want to use the one in that picture because it looks like it'd be more suitable for a pet. That one would make your hair frizzy.

I believe this thing is called "call and response spam."
