An apparatus that focuses on improving efficiency, profitability, and results in the automotive detailing and automotive paint and body shop industries, contains a first layer, a second layer, and a center layer. An inner surface of the first layer is connected to the center layer. An inner surface of the second layer is connected to the center layer opposite to the first sanding layer. The multiple tiers of the apparatus improve user control and maximizes surface contact between the apparatus and the surface being sanded. A first edge and a second edge of the first layer and the second layer can be a straight-cut edge, a bevel cut edge or a rounded edge. Thus, the apparatus can be used on a variety of surfaces. The consistency and the uniformity of the sanding patterns obtained helps the user compound and polish the sanded surface to a more refined finish.

Sanding devices disclosed herein include a rigid member, a flexible member permanently coupled with a bottom of the rigid member and with a portion of a top of the rigid member, and a sanding member permanently coupled with the flexible member. In implementations the sanding member consists of sandpaper. The flexible member may be shaped substantially similar to, or identical to, the sanding member in at least two dimensions. A front of the rigid member may have a rounded end and the rigid member may be tapered and larger in front than in back. The flexible member may form a pair of upper wings extending outward past sides of the rigid member at the top of the rigid member, a pair of lower wings extending outward past sides of the rigid member at the bottom of the rigid member, and a tail extending past the back of the rigid member.

A surface processing device, in particular a manual grinding device, includes a processing body which has at least one processing surface for grinding or polishing a workpiece surface, wherein inlet openings are arranged on the at least one processing surface for suctioning off dust-laden dust air and these inlet openings are flow-connected via a duct arrangement to a suction connection to which a suction device can be connected. The surface processing device is provided with an adjustment means for adjustment of effective flow cross-sections, with which inlet openings of a first processing surface section of the at least one processing surface and inlet openings of at least one second processing surface section of the at least one processing surface are flow-connected to the suction connection, so that a suction effect on the first processing surface section and the at least one second processing surface section can be set and/or switched off.

A sanding block produced by co-extrusion of a substantially softer polymeric material and a substantially harder polymeric material is described. The substantially hollow interior of the co-extruded body of the sanding block may be sealed by first and second plugs that seal the opposite longitudinal ends of the hollow sanding block section to enable drawing suction through the sanding block, such as for use with a vacuum device.

Described is an apparatus for finishing metallic and non-metallic surfaces by abrasion techniques. Described is an apparatus configured for finishing a zone on the surface of a bladed article of manufacture, wherein the apparatus comprises one or more channels having a cross-sectional profile including at least one finishing area to finish an operative zone of the article that optimizes a clearance portion of the article, wherein an angle of each finishing area of the cross-sectional profile is substantively the same as an optimal clearance angle of the article, wherein the apparatus is configured to position the operable zone of the article along the angle of the finishing area during sharpening.

A masonry device is provided. The masonry device is dimensioned and adapted to operatively associate with a sickle stone so that a mason may utilize sickle stone through a handle portion of the masonry device. The masonry device may include a sleeve defining a saddle void for receiving the sickle stone. A locking mechanism is provided for removably securing the sickle stone in the saddle void during use. As a result, a user of the masonry device may manipulate the sickle stone without directly handling it, as well as use sickle stone to its last inch.
