Philips Norelco OneBlade First Shave Teen shaver uses revolutionary cutter to power any length of hair. 200 cuts per second for a fast, clean shave. A protective plate on the top of the cutter, with a rounded tip instead of a pointed tip, allows the blade to slide smoothly - which is why OneBlade helps protect the skin from nicks and cuts. In addition, we added a layer of microglass beads to reduce friction during shaving and help reduce razor burns.
