The Laube Lazor CX Size 4 is a skip-tooth detachable blade with a nominal 3/8-inch cutting length, marked as 9.6 mm by Laube. It gives groomers a longer cutting option than the Size 5 while retaining the alternating tooth pattern of the skip-tooth range. Match the size number and tooth layout when replacing a blade already in use.

The blade attaches to compatible clippers through the standard snap-on system. This makes the blade size a separate choice from the handpiece: a groomer can exchange compatible blades as different cutting lengths are needed. Confirm the attachment system before ordering. Laube excludes the #305 Speed Feed and trimmers from fit.

Maintain lubrication and remove hair buildup from the cutting surfaces. Laube's blade-cooling spray instructions call for stopping the clipper before application; follow the care product's directions.
