There are 3 types of blades. The Carver, Forte and Baron. The Carver is recommended for coarse hair, the Forte for most users, and the Baron for sensitive skin and/or fine hair. All of them give a great shave but the comfort level changes depending on your personal preference and skin type. There are also 3-head, 4-head, and 5-head models. The 5-head models have a strong following and many people fell in love with Skull Shaver using this blade. The 5 head was th eoriginal Skull Shaver design that won many over. However, as much as we love them, the new PRO blade technology, which is utilized on all 3-head and 4-head models, has many improvements. We listened to customer feedback and improved the 5 head design with the new PRO design. We allowed the blade to be opened for easier deep cleans and also sealed the drivetrain. With these improvements there should be less wear and tear on the blades and the motor giving your shaver and blades a longer life and you a more comfortable shave. The 5-Head and 4-Head models are meant to cover large areas quickly and are intended to shave the entire skull quickly and efficiently. The 3-Head blades are designed specifically for the challenges of shaving the face. The smaller blade profile more closely conforms to tightly contoured areas such as your chin or jawline. Any of our blades will give a quick, painless, smooth shave but the best blade for you is ultimately up to you. Hopefully this helps to get the best shave possible.
