The Wahl 1026-400 is a replacement animal clipper blade set for close clipping, identified by the manufacturer with the 40–30 surgical designation. Wahl specifies a cutting range of 0.5–1.2 mm, making this a blade for tasks where very little hair should remain. The cutting surfaces are precision ground to establish a sharp edge and support durability through use.

The manufacturer's listed package includes the blade, blade oil and screws, providing the cutting component together with mounting hardware and lubricant. Match part number 1026-400 to the replacement blade specified for your clipper before fitting it.

Regular lubrication helps preserve cutting performance. Brush out accumulated hair after use and apply clipper oil before the next session. Wahl also recommends restoring the oil film after cleaning to help protect the blade against corrosion during storage.
