For daily beard maintenance or for making a big change to facial hair, Wahl's Groomsman trimmer is the device you need. The Groomsman's high-carbon steel blades are precision-ground to provide a close cut and stay sharp longer. A six-position beard regulator easily attaches to the trimmer's head to provide consistent and safe tapering and trimming of beards and mustaches. The six positions range from a height that tackles longer hairs, (for example, if you are shaving off your beard) all the way down to a short height for trimming daily stubble. For convenience, the beard regulator remembers the last set length height until you change it.
