From Wahl Professional s salon-quality line, the 5-in-1 Adjustable Replacement Blade is designed for slicing, feathering, and texturizing hair. This standard-size replacement blade delivers professional-quality performance and is compatible with the Wahl Professional ChromStyle Pro Cord/Cordless Clipper, Sterling Li Plus Pro Clipper, and Sterling Big Mag Clipper. To use, firmly grip your clipper and press the blades away from the front so they come off in one piece. Then snap the bottom tab of the blade chassis into the designated area in the trimmer housing. Before use, ensure the blades are properly lubricated for smooth operation and to help prevent pulling hair or pinching skin. Wahl blades are made to high standards and sharpened, finished, and tested for exceptional sharpness, durability, and long-lasting use.
