Combs can be used with the Wahl KM-2, KM-SS and Switchblade clipper. Wahl Stainless Steel Attachment Combs must fit snugly on the blade set. For best performance use the Wahl Stainless Steel Attachment Combs with the Wahl #30 Competition Blade sets, however they can be used with most other sizes. DO NOT USE ON A #40 or #50 BLADE SET. DOING SO WILL BREAK TEETH.
