ABSTRACT:
The scissor sharpening machine includes a honing disc with a curved blade guide and a blade clamp assembly which slides axially along the blade guide. The curvature of the blade guide corresponds to the conventional curvature along the lengths of the blades of a pair of high quality scissors or shears, and assures that they are sharpened properly. The blade clamp assembly includes a series of predetermined stops to set the proper bevel angle during the sharpening process. However, the blade may be rocked about its longitudinal axis to the limit set by the stop, in order to provide a convex curvature to the blade edge if so required. The apparatus may include a cabinet with motor controls and other components, and the blade guide and blade clamp assemblies may be adjusted and repositioned to allow sharpening of either left hand or right hand scissors and shears.
