1. A tool adapted to hold abrasive material comprising:

  • a base having a top surface and a planar bottom surface for extension of a strip of abrasive material therealong;

    a pair of opposed end walls normal to said bottom surface of said base;

    a pair of sidewalls extending between said base end walls;

    a plurality of prongs extending from said top surface of said base, said prongs adapted to extend through the ends of the strip of abrasive material overlapping said base end walls and extending along said bottom surface of said base;

    a releasable handle having a top surface and a bottom surface extending between a pair of opposed end walls;

    a pair of opposed handle sidewalls extending between said handle end walls, one handle sidewall having a greater height than an opposed handle sidewall above said base, said bottom surface of said handle having a configuration complementary to said top surface of said base to present a contiguous fit therebetween;

    means for receiving said prongs of said base within said handle with the abrasive material ends in a contiguous fit between said handle bottom surface and said base top surface;

    said handle top surface comprising a contoured surface, said contoured surface presented by an arch-like surface longitudinally extending between said opposed end walls of said handle, said arch-like surface presenting a first laterally extending portion increasing in height, relative to said base, as said top surface laterally extends from one handle sidewall to said opposed handle sidewall to a region on said handle top surface displaced from said one handle sidewall, said arch-like surface then presenting a second laterally extending portion successively decreasing in height relative to said base, as said arch-like surface laterally extends from said region to said opposed handle sidewall, said first laterally extending portion of said arch-like surface at a greater height, relative to said base, adjacent said one handle sidewall than the height of said second laterally extending portion of said arch-like surface adjacent said opposed handle sidewall, said greater height of said first laterally extending portion adjacent said one handle sidewall adapted to be contiguously positioned underneath the index finger and adjacent fingers of a user with said height of said second laterally extending portion adjacent said opposed sidewall adapted to be contiguously positioned underneath the ring finger and adjacent fingers of a user grasping said handle.
