Wahl Adjustable Blade, Size 30-15-10 (1037-400)

The Wahl 1037-400 is a standard replacement blade for Wahl adjustable-blade animal clippers. It carries the 30–15–10 designation and provides a manufacturer-listed cutting range of 0.8–1.8 mm. For owners maintaining a compatible clipper, it replaces the cutting component while retaining the machine's adjustable-blade setup.

Wahl specifically lists the Multi Cut 9269, U-Clip 9281 and Lithium Pro Series 9766 as compatible models. Checking that model number alongside the blade part number helps identify the correct replacement for your equipment. Precision grinding creates the blade's cutting edges and supports their durability.

To keep the blade working properly, brush hair from the cutting area and lubricate it regularly with clipper oil. Wahl recommends oiling at the start of the day and again when the clipper is used heavily. After cleaning the blade, replenish its oil film to help protect the cutting surfaces before storage.
