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.
