Review (5/5): It's a Razor Handle
It's made out of plastic and the blue raised ribs are rubbery, which I'd guess makes it easier to hold with wet soapy fingers. I'd also guess you could snap it in two with your hands, but why would you do that? If you were using it to shave, and you put enough pressure on it to break it, you would bleed to death long before you needed another shave.
If you have Sensor blades and need a handle to use them, this is it.
