A device for filing and/or abrading the multiple surfaces and/or edges of an object end so that they are less sharp, rough, dangerous, or so that they better conform to a desired shape. Embodiments of the device may comprise filing surfaces for filing the multiple object surfaces and/or edges thereof without requiring substantial repositioning of either the device or the object with surfaces and/or edges being filed. Moreover, embodiments of the device may be useful for filing sets of both the inner and outer object surfaces and/or edges thereof without requiring substantial repositioning of either the device or the object, and therefore in a more efficient and less dangerous manner. It is anticipated that some embodiments may comprise filing surfaces arranged in a manner configured to file the surfaces and/or edges of a strut end.

A hand-held sanding block used by a hand of a user, replaceably holds sheet sandpaper, prevents the sheet sandpaper held therein from unintentional removal therefrom during use, and does not collapse under heavy pressure from the hand of the user during use. The hand-held sanding block includes a body. The body is used by the hand of the user, replaceably holds the sheet sandpaper, prevents the sheet sandpaper held therein from unintentional removal therefrom during use, and does not collapse under the heavy pressure from the hand of the user during use.

An adjustable sanding block that allows for expedited interchanging of sandpaper belts by removing a lateral tension on the belt and reducing the length of the sanding block. A spring loaded heel and a block make up the sanding block, forming a coplanar relationship with opposed inner ends. A rod and spring on the block create a lateral tension against a recess in the heel that retains the belt on the sanding block. The rod and the spring extend from a block inner end, engaging a recess in the heel. The rod passes through the recess, while the spring, having a larger circumference, compresses against a periphery of the recess. This compressive force creates an outward lateral force, which creates lateral tension on the belt for retaining the belt on the sanding block. Applying an inward pressure on the heel removes this tension for mounting and removing the belt.

A cleaning and drying device utilizing removably attached material that includes a material plate, two material retaining clips, and a handle or hand grip. The two clips are hingedly attached to the plate. When upward pressure is applied, the clips pivot upward from a center point, thereby upwardly-extending an outer edge of each clip. An edge of a material is then inserted between each clip's outer edge and the material plate. When pressure is removed, the two clips are forced downward, thereby trapping the material between the clips and the plate. Once the material is secured, the device can be used to clean or dry a surface. After cleaning or drying, the material is removed and a new material is attached. The material can be any fabric/cloth including rags, old clothing, towels or any other material, thereby precluding the requirement to use special pads or other proprietary materials.

The invention relates to finishing metallic and non-metallic surfaces by abrasion techniques. In certain embodiments, the invention pertains to 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.
