Bravo's Ceramic blades are designed to give a smoother and faster cut. The superior wear resistance leads to longer working life. You will see a significant change in your clippers and trimmers heating up, performing considerably cooler than the original metal blades. Ceramic blades stay up to 75 percent cooler than steel blades when used over long periods of time, since they conduct less heat than steel blades. CERAMIC BLADES DO NOT HEAT UP. Bravo Barber Supply insists for ALL barbers to incorporate ceramic blades to any of your clippers and trimmers. * 4x Shaper * 4x Cooler * 4X Longer working life * Less coolant * Less oil * Reduce risk of friction * Rust Free * Corrosion Free
