A surgical blade includes an elongate outer tubular member, an elongate inner movably received within the outer member, and a polymer coating disposed on a portion of the outer surface of the inner member, the inner surface of the outer member, of both. The inner member has a distal cutter positionable adjacent a distal opening in the outer member. A method of cutting tissue, e.g., hard tissue such as bone, includes providing a surgical blade having an inner member and/or an outer member coated with a polymer, placing the surgical blade against the tissue, and driving the inner member to cut the tissue.
