  • Patent number: 8549755
    Abstract: A compact utility knife includes a blade holder slidably connected to a handle. A trapezoidal utility blade detachably mounts to the blade holder via a blade lock mechanism. A slide lock mechanism selectively retains the blade holder in its extended or retracted position relative to the handle. When the blade holder is extended, the blade holder and a majority of the blade extend forwardly of a forwardmost point of the handle. Extending the blade holder significantly increases an overall length of the knife such that the knife is comfortable to use when in the extended position and longitudinally compact when in the retracted position. The knife includes a blade lock mechanism. An aperture in the front of the handle creates a gap between the blade and the handle to discourage debris on the blade from transferring to the handle when the blade is retracted.

  • Patent number: 8136251
    Abstract: A hand tool includes a holder and a movable head portion to which a blade body is secured. The movable head portion is supported by the holder in a manner movable relative to the holder between an accommodated state Q, in which the movable head portion is accommodated in the holder together with the blade body, and a projected state, in which the blade body is projected from the holder. The orientation N of the blade body in the accommodated state Q and the orientation N of the blade body in the projected state are different from each other. This improves operation of the blade body both in the accommodated state Q and the projected state and reduces the size of a front opening of the holder to provide a compact holder of the hand tool such as a medical edged tool.
