Clipper Blades are sharpened using the Nebraska Blade system. Your blades are returned quickly, clean and sharp. All blades are inspected for damage then washed in biodegradable degreaser, without harsh solvents, leaving a fresh and pleasant scent. They are then sharpened, demagnetized and oiled. The sockets are then reset and the tension springs are adjusted before being reassembled. Every blade is tested to guarantee sharpness and quality before individually wrapped and packaged.
