Abstract
An apparatus for sharpening a blade having a base member with a slot for receiving and guiding a blade to be sharpened, first and second apertures disposed on either side of the slot, first and second resilient biasing members disposed in association with each of the first and second apertures such that each of the biasing members is substantially entirely enclosed within rear spring caps and protected from debris and contaminants. Sharpening members are connected to the biasing members and are rotatable about a central axis of each respective aperture between a first and second position, which rotation is limited by a stop member as the blade passes from one end of the slot toward the other. The durability of the base is enhanced with top guide rails so a blade entering the slot cannot cut into the base member.
