What's the difference between a traditional razor blade and an electric razor? What does aftershave do?

Traditional shavers need to soak the beard in warm water before shaving, while electric shavers need to be dry and hard before shaving. One is to scrape the beard off the face by the sharpness of the blade, and the other is to insert the beard into the razor net and cut it off by the shearing force between the moving knife and the net cover. High-performance and high-quality electric shaver is as clean and safe as traditional shaver after shaving.
