ABSTRACT:
A hand-held, hand-operable, abrasive tool (10) comprising: i) a handle (11) having a trapezoidally shaped insert mounting slot or aperture (12); ii) a rigid replaceable insert (14, 14', 14") having a work engaging face (18, 18',18") of desired shape and size and a trapezoidally shaped mounting pedestal (19) adapted to be snugly received within, and frictionally retained by, the trapezoidally shaped slot or aperture (12) in handle (11); and iii), a multi-pack (15, 15', 15") of adhesively edge-bonded abrasive sheets (16) which can be adhesively affixed to the work engaging face (18, 18', 18") of the rigid replaceable insert (14, 14', 14") in conforming face-to-face relation; and, wherein an expended abrasive sheet (16) can be discarded merely by peeling that sheet off the multi-pack (15, 15', 15") to expose the fresh, unused, underlying abrasive sheet (16), and inserts (14, 14', 14") can be easily replaced by merely applying pressure to the dome-shaped crown (20) on the pedestal (19) mounted in the handle (11) to eject the same.
