The Laube Lazor CX Size 4F is a full-tooth grooming blade with a nominal 3/8-inch cutting length, marked by Laube as 9.6 mm. It provides a longer cutting option than the 1/4-inch Size 5F while retaining the full-tooth layout used for finishing a combed-out coat. The size and F marking together identify the correct variant.

This blade uses the standard snap-on attachment found on compatible detachable-blade clippers. That format lets a groomer change the cutting length by changing blades on the same suitable handpiece. Confirm that your clipper accepts this blade system before ordering a replacement. Laube excludes the #305 Speed Feed and trimmers from compatibility.

Clean and lubricate the cutting surfaces using suitable blade-care products. Laube explains that its blade dip can loosen residue, displace water and protect against rust; follow the product instructions.
