20090000132 | REDUCED VIBRATION SAW HANDLE - A saw handle for reducing the amount of vibration transmitted to a user during use of a saw. The handle includes a resilient material of lower durometer than the blade mount and is interposed between the blade mount and the user's hand in order to absorb and reduce the vibrations transmitted to the user. In one configuration, the resilient material is interposed between the blade mount and the handle in order to isolate handle from the blade mount. In another configuration, the handgrip is of a resilient material devoid of an internal structure. In yet another configuration, the handgrip is of a resilient material with an internal structure, where the internal structure may have an overlapping or non-overlapping configuration. | 01-01-2009 |
20090193665 | COMPACT UTILITY KNIFE - 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. | 08-06-2009 |
