I'm letting my beard grow in for the second time. Currently I look like I've been on a 5 day bender but it's starting to fill out. My question is, what is a good beard/mustache trimmer? The last time I had grown my beard my mustache got thicker than I cared for. When my wife cuts my hair, she would trim back my beard with the same guard but the mustache would grow back quicker than my hair. Any hints or tips are greatly appreciated. And yes, I will up date my avatar when the beard is fully operational.
