  • Patent number: 7263775
    Abstract: An illuminating nail clipper for clipping the nails of an animal such as a dog, cat, bird, or the like which allows for the clipping of an individual nail at the desired length to prevent injury or improper length cutting for the animal. The device includes a hand-actuated clipping blade used in conjunction with an adjustable in size nail holder which includes a cutting hole and which allows the nail to be clipped to be firmly held at a particular position relative to the nail cutting blade. A light source illuminates an animal's nail to make it translucent, allowing the operator to see the capillaries within the nail and thus to avoid cutting to the live portion of the nail.

  • Patent number: 7249552
    Abstract: A guide for use with a cutting member, such as hand saws, that is easy to use, is readily portable and can be adjusted to permit cutting of precise compound angles on work pieces of various configurations. The guide mechanism comprises two angularly related members arranged so that when one member engages the face of a work piece, the other member functions to glidably engage a cutting member, such as the blade of a hand saw with the teeth thereof in cutting relation with said face of the work piece. In one form of the invention, locking mechanisms are provided to lock the member in any selected angular relation and a magnet is carried by the guide member which uniquely functions to continuously urge the saw into engagement with a plurality of rollers that are also carried by the guide member.
