I've decided to grow a beard, and as such I'm new to the idea of "trimming." I've heard of people using a comb to grab some hair and use an electric razor to trim the excess hair length off of the comb, but I'm wanting something where I can push against my face as hard as possible while still only cutting the top half of the beard or so.
Does that make sense? Is there a razor or razor accessories that can do this? What do you suggest?
