I use this: https://www.amazon.com/Schick-Quattro-Trimstyle-Bikini-Trimmer/dp/B001TH8Q72

I like my pubic hair very short. Heck, I even shave bald most of the time but this trimmer/razor combo is great in general.

I even use the trimmer to groom my super hairy arms.

Not gonna lie, my wife's $10 schick with a trimmer on it. Works pretty well, it's lightweight, compact, and the trimmer portion is adjustable. I also have sets of Wahl and Andis clippers. Depends on what I'm scaping as I'm a midget sized wookie.
