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 file handle has a body, a ferrule, a clamping assembly, and a cap. The body has a first end and a second end opposite to the first end. The ferrule is assembled at the first assembling end of the body. The clamping assembly is movably mounted in the body and has two clamping portions and a threaded hole. The two clamping portions extend through the ferrule. The two clamping portions are subjected to an elastic force and oppositely separated from each other. The threaded hole is adjacent to the second assembling end of the body. The cap is rotatably assembled at the second assembling end of the body and has a screwing stick screwed in the threaded hole. Because the space between the two clamping portions can be adjusted by turning the cap, a user can clamp a tang of a file blade by the file handle.

A multi-tool includes a keyshaped body, the keyshaped body having a key like shape and a standard key size. The keyshaped body includes a rounded end, the rounded end including a aperture for a key chain and a textured surface configured to provide grip to the hand of a user. The keyshaped body further includes a slim extending end, opposite the rounded end, the slim extending end including a tip, the tip having a wedge end, the wedge end shaped such that it functions as a screw driver, the slim end further included a left and right side, the left side having a grooved surface shaped such that it functions as file, the right side including a cutting surface and a lip, the lip providing for a bottle opener in conjunction with an aperture in which the cutting surface is located and using the keyshaped body as a lever arm.
