Abstract: The present invention relates to a flexible abrasive article for grinding or polishing and a method for making the same. The flexible abrasive article has a fabric substrate and at least one abrasive layer provided thereon. The abrasive layer is a composite with an adhesive binder in which diamond particles and metal particles are distributed to form an interpenetrating array of diamond particles and metal particles. It is preferred that the metal particles be about equal to or coarser than the size of the diamond particles. It is still further preferred that the abrasive layer include a distribution of non-metallic filler particles interspersed with the diamond particles and the metal particles. The method of making the flexible abrasive article described above can be accomplished by selecting a fabric substrate, preparing an abrasive coating mixture by first mixing a resin with a volatile carrier, second mixing in the particulate components, and applying the mixture to the substrate in one or more layers.

Abstract: A folding knife is provided which has a blade, a main handle and a tail handle. The tail handle is pivotably engaged to the main handle. When the knife is in a work configuration, a free end of the tail handle is swung to engage a blade end of the main handle and, together with the main handle, the tail handle forms a grip from which the blade extends. Both the main handle and the tail handle have grooves, such that when the tail handle is swung away from the main handle into an open position, the handles together form a sheath for the blade. With the main handle and the tail handle so configured, the blade of the folding knife can be longer than the grip and yet still be sheathed when the blade is swung into the sheath formed by the main handle and the tail handle for storage. The knife preferably has a tip encasing assembly attached to the tail handle which prevents the blade from being accidentally disengaged from the sheath.
