A blade set for a hair clipper including a movable blade constructed of ceramic. The movable blade includes an upper surface having a pair of integrally formed upper reinforcing protrusions. The upper reinforcing protrusions are disposed adjacent to a drive notch sized to receive a drive finger of the hair clipper. Reciprocation of the drive finger results in a cutting action of the blade set.
