ABSTRACT:
A laterally flexible and generally inflexible longitudinally hand-held sanding device. The device includes a generally tubular walled body of tough rugged semi-rigid resilient material which is generally cylindrical in its normal relaxed at-rest state. A longitudinal slot extends the length of the body severing the body wall to facilitate lateral flexing. A pair of spaced apart parallel angularly and inwardly extending tapered lips define the opposite sides of that slot. The sander may be flexed to accommodate a variety of contours to be sanded. It may be used in association with sheets of sandpaper or other abrasive material, or abrasive material may be embedded in the body of the sander, either at the outside surface or throughout the body.
