Abstract: An edger for manually refurbishing elastomeric wiper blades has a housing to be grasped by a user, the housing having a groove with rigid, non-abrasive sidewalls spaced substantially the same as the width of the working edge of the blade, and an abrasive member disposed in the housing at the bottom of the groove, the abrasive member aligned transverse to the groove to remove material from the blade transverse and perpendicular to the blade, effectively smoothing the blade as the edger is passed along its edge. The abrasive member may be mounted in the bottom of an inverted T-shaped slot, or the housing may include a slotted external member and an internal member defining a flat surface for supporting the abrasive member behind the slot.
