The Gamma+ THE ONE Deep DLC Black Diamond Cutting Blade is compatible with all Gamma+ and StyleCraft trimmers. Secure black runner to blade for Evo and X-Evo/Secure white runner to blade for Hitter, Power Cruiser and Protg. "THE ONE" blade is ideal for sensitive skin and finishing with the crunchiest and smoothest cutting, without pulling or snagging. Enhanced cutting performance with super sharp tips and a lightweight, slim design for faster movement. Japanese black diamond steel is rust and corrosion free, staying sharper for longer with the coolest operation. HOW TO REPLACE THE BLADE - This blade replaces the moving cutting blade. Simply unscrew the two screws on the trimmer, gently remove the old blade, replace with this one, and reinstall screws into machine. Make sure blades are aligned properly before turning on. Depending on your daily use, it is recommended to change your blade every 1 to 4 months for maximum performance. To clean your blades, gently brush to clear debris, spray blades with disinfectant (optional), oil clipper, wipe clean with a dry cloth and use blade cover for storage. | Gamma+ Unisex THE ONE Deep DLC Black Diamond Cutting Blade for Trimmer
