Sugars and Spice

Hi. I was wondering if anyone knew if a tool existed to flatten chicken easily and more evenly. I know how to do it conventionally, with wax paper or plastic wrap and a Rolling Pin or meat mallet. I'm not particularily good at it, and it's a bit of a pain in general. I was thinking there must be something to make the process easier and more even.

I was thinking something akin to those manual aluminum can crushers or perhaps a vice or some kind, but I can't seem to find anything like that online. Does anyone know if anything like this exists?

Thanks!
