An elastic self-lubricating polishing tool includes an elastic grinding layer including an abrasive member and an elastic base layer affixed to the abrasive member, an absorbing layer absorbing and sustainedly releasing liquid inside of the absorbing layer, and an adhesive layer overlappedly connected with the elastic base layer of the elastic grinding layer and the absorbing layer. The elastic self-lubricating polishing tool is elastic and self-lubricating to sand and polish a surface of a workpiece.

A paint trencher includes a main body, an abrasive body, and a handle. The main body includes a top panel, a bottom panel, and a support. The abrasive body, preferably a beveled-elongated body, is adjacently mounted to the support in order to cut into the wall. The handle is mounted to the top panel so that applied pressure of the main body can be transferred into the abrasive body thus cutting a trench into the wall. A felt pad is perimetrically attached around the bottom panel so that the surrounding wall area of the trench can be protected from unnecessary scratches.

A hand-held sanding apparatus has an adjustable flexibility. The sanding apparatus includes a flexible handle with a plurality of preformed rod channels. One or more rods are configured for insertion into the rod channels, wherein the one or more rods adjust a flexibility of the sanding apparatus. A flexible base member is attached to a lower surface of the flexible handle and includes a precisely smooth bottom surface configured for attachment to an abrasive material. The flexible base member may comprise a polycarbonate material, and the flexible handle may comprise a rubber material.

A sanding block adapted for abrading a surface, particularly drywall joints, comprising: (a) a body having an array of elongated raised portions having raised end surfaces and recessed portions, the raised end surfaces collectively defining an abrasive working surface and the recessed portions defining channels between adjacent raised portions; (b) a make coat on the end surfaces; and (c) abrasive particles at least partially embedded in the make coat. Also methods of using such sanding blocks.
