A sanding device (1) includes a base plate (3) with opposite sanding and supporting surfaces (5,7); as well as a joint (29) operatively mounted onto the supporting surface (7) of the base plate (3) and rotatable about a first axis of rotation (93). A supporting tube is (69) operatively mounted onto the joint (29) and rotatable with respect to the joint (29) about a second axis of rotation (95).

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.

An object of the present invention is to provide a porous material for polishing in which, during a polishing operation, it is possible to keep a proportion between abrasive grains in contact with an object to be polished and a resin portion in contact with the object to be polished within a certain range, even if an unskilled person attaches a polishing tool to an automated device and uses it, there is no need for complicated adjustment to stabilize the device, whereby it is possible to obtain precise surface accuracy. The above object is achieved by a porous material for polishing including an elastic foam having anisotropy, a polymer, and abrasive grains.

The invention relates to apparatus for polishing a running base that comprises a blade with two opposing blade edges separated one from the other by an intermediate section; the polishing apparatus comprising: a support body, and blade alignment guide means; wherein the support body is capable of carrying a polishing surface which comprises: a profile which is adapted to conform with one or more portions of the intermediate section; and wherein the blade alignment guide means comprise one or more pairs of first and second blade alignment guides, which first and second blade alignment guides in each pair are separated from each other by the polishing surface, and further wherein the blade alignment guide means is adapted to receive and/or guide and/or constrain a running base so that when the intermediate section between the two edges of the running base is brought into contact with the polishing surface, there is no contact between the polishing surface and any part of the two opposing blade edges of the running base.

A simple hand held label degrading device and method employs a molded polymer ring (collar) having a plurality of molded hardened pointed teeth on the internal circumference projecting radially inward for degrading the label of a prescription bottle or the like inserted therein. A longitudinal slot in the collar allows it to be fitted over a bottle such that simple hand squeezing of the collar compresses the collar around the bottle and engages the pointed teeth against the label. Simple hand twisting of the collar around the bottle in a clockwise or counterclockwise rotation cuts through the plastic composite or paper label and shreds the label rendering sensitive information illegible thus protecting personal health information. The bottles can then be thrown away or recycled without fear of medical identity theft.

Embodiments of sanding systems and methods for using and making the same may include providing a sanding system, comprising a body and a core. The body may be defined by at least a plurality of faces including a proximal face and a distal face and further defined by a hole extending lengthwise from the proximal face at least partially through the body toward the distal face. The core may be configured to be disposed at least partially within the hole such that changing an extent to which the core is disposed within the hole changes a density gradient of the sanding system.

The handheld cleaning apparatus provides a handheld cleaning apparatus comprising a removable handle, abrasive particles, angled edges, open channels, and a flexible yet durable surface for scouring. The invention creates an abrasive, or sanding, cleaning apparatus that is better suited for cleaning dirty surfaces than a traditional cleaning sponge. The handheld cleaning apparatus retains the abrasive outer shell of a sanding sponge but is much more flexible and water permeable than current sanding sponges. To this end, the handheld cleaning apparatus comprises open channels, or blow holes, that promote water flow through the sponge and give the sponge flexibility. The size and the number of the channels vary by the material or density of the sponge. The handheld cleaning apparatus, additionally, contains a handle that is removably attached, which enables the consumer the ability to connect one or more cleaning apparatuses together to form the desired shape and form of the cleaning apparatus.

Sanding pads are disclosed. A sanding pad has at least about 1/32 inch thickness, having one top flat surface and an opposite flat bottom surface. The top and bottom surfaces are capable of providing attachment for an abrasive material, such as a pressure adhesive sand paper. The sanding pad is formed of various geometric shapes and made from an expanded PVT material which has a Shore D durometer hardness value between 30 and 60. The sanding pad comes in a kit that includes several sanding pads, each of a different shape and situated purpose.
