  • Patent number: 4648415
    Abstract: Nail clipper of the leaf spring type in which the leaf spring elements of the clipper are superimposed and have facing inturned cutting edges at their proximate ends and are riveted together at their distal ends. A post extending through the leaf spring elements close to the proximate ends thereof forms a reaction member for a lever moving the leaf spring elements together to effect a clipping operation. Extending partially about the post and facing the cutting edges of the leaf spring elements is a nail clipping decelerator and accumulator formed to prevent the flying of nail clippings beyond opposite edges of the clipper and to accumulate the clippings for disposal by opening the clipper and shaking it in a sideways direction.
