To keep shaving hygienically, you need to replace the shaver blades every 4 months. The OneBlade shaver blades feature a system that shaves hairs with up to 200 movements per minute. This high speed means that the shaver blade is suitable for both short and long beard growth. In addition, the blades have a smooth coating and rounded ends, so they protect your skin and prevent skin irritation. To keep the shaver blades clean, rinse them under the faucet after every shave.
