The Peanut trimmer from Wahl is ideal to manscape with because of it's small size and ease of handling in tight place. It also has a narrower and finer-tooth cutting blade thats better for precision trimming and edging needs - unlike a full-size home hair clipper with much larger and coarser blade. That makes it ideal to manscape a beard, mustache or goatee as well.
Prefer a cordless model for your manscaping sessions? Wahl also makes a cordless Peanut trimmer that runs on an AA NiMh battery and includes a charger and two batteries so you'll always have a spare battery ready to go. That said, as a manscaper, I personally prefer AC wall powered clippers that simply have more hair and whisker whacking power in general, and keep cutting even through long, full body head to toe bearscaping.
NiMh Batteries + Charger Included
Another one of the nice things about this handy little tool for body grooming and manscaping is (like all of Wahl's product line) both replacement blades and guide combs are readily available. You can find replacement parts online and at many hair salon product shops like Sally's Beauty Supply should you lose, damage or otherwise break a comb or blade.
