Wahl Professional 5 Star Series Cord/Cordless Magic Clip Full Size Hair Clipper with Precision Blades Lithium Ion Battery and 100 Minute Run Time for Professional Barbers Stylists Are the blades sharp enough to cut the skin? Under normal operation, Wahl Clipper and Trimmer blades set at the factory should not cut the skin. Dropping or the hitting the blades can knock them out of alignment and could result in nicking the skin. Always inspect your blades prior to use. How are the finishing tools to be used? Wahl Professional Finishing tools can be used in a variety of ways. Shavers can be used on the neck, face, top of the head, and as a blending tool! Can human clippers/trimmers be used on animals and vice versa? Wahl Professional products can be used on animal hair. However, the blades are designed to cut human hair. The best option is to consider one of our professional animal clippers designed specifically for animals. Can my Wahl Professional Clipper/Trimmer be zero-gapped? Everything in the 5-Star line is designed to be zero-gapped and allows you to get the closest cut to the skin possible for sharper lines.
