Hand tool having a cushioned laminate attachment surface

Abstract

A hand tool which includes a cushion member of a construction which is capable of preventing the separation of a cushion member due to frictional heat and force generated during the grinding operation. The abrasive hand tool includes a tool body having a generally flat bearing surface and a thin sheet-like cushion member fixedly secured to the bearing surface of the tool body. The cushion member includes an inner layer fixedly bonded to the bearing surface of the tool body via an adhesive and an outer layer layered and bonded with the inner layer. The outer layer defines on the outer surface thereof a generally flat attachment surface for detachably holding an attachment means-backed abrasive sheet. The inner layer is made of a soft resinous foam, such as polyvinyl chloride resin, polyurethane resin or others. The outer layer is made of a sheet of material which is preferably the same as and harder than the inner layer, and bonded to the inner layer without using an adhesive by a fusion-bonding process such as a high frequency bonding process.
