  • Patent number: 6428407
    Abstract: A multi-grit manual finishing tool and method for making the tool. In a preferred embodiment, the tool comprises an ordered, linear sequence of pieces of coated abrasive connected by fully pliable hinges. The hinges allow virtually 360° rotation of the planes of adjacent pieces about each other, and permit the tool to accordion-fold together tightly, so that the tool becomes very compact for storage, transit and special uses. The grit sizes progressively increase from one abrasive piece to the next, thereby facilitating a choice of grit sizes within a single tool. On the non-grit surface of each piece is a distinctive labeling addition that includes indicia characterizing the grit size and abrasive nature of its corresponding grit surface. The distinctive labeling addition includes mechanical reinforcement, such as plastic, thin metal or cardboard. Each piece may abrade a work piece individually and without necessarily using any tool other than hand or fingers.
