Merkur Clipper is an entirely manual hair trimmer that operates without electricity or batteries. Its stainless steel cutting edges provide a gentle, safe hair-removing experience that requires only a few turns of the lower handle's cross-knurl grip for dynamic rotation. To preserve the long-lasting sharpness of your clipper, avoid bumps on the cutting edges, and use its unisex design only with hair. Clean the blades with a brush and occasionally lubricate them with a few drops of resin- and acid-free oil, such as medicinal white oil. To ensure thorough cleaning, the two parts can be detached by loosening the screw.
