ABSTRACT:
A sanding block having a handle portion from which projects an elongate support portion to which can be adhered a strip of pressure-sensitive adhesive-coated finishing material. The support portion has various shaped surface portions for supporting the finishing material, including a planar surface portion, an arcuate surface portion of decreasing radius extending longitudinally of the support portion away from the handle portion, and an edge surface portion provided by planar surface portions intersecting at an acute included angle so that the finishing material may be supported in a desired shape that affords pressing and rubbing it against a complementary surface on a workpiece by manual manipulation of the sanding block.
