File with sanitizing agent

Abstract

A file includes a support member having an abrasive surface with interstices holding a sanitizing agent which is released with use of the file. Microcapsules containing the sanitizing agent are preferred. The microcapsules are frangible and break upon use of the file to release the sanitizing agent. The file surface may comprise granular abrasive particulates having a size ranging from 40 to 1200 grit which provide the interstices between at least some of the particulates. An aqueous coating having dispersed therein an adhesive and the microcapsules is applied to the granular particulates. The coating is dried to deposit in the interstices the microcapsules. The adhesive binds the microcapsules to the granular particulates.
