  • RETRACTABLE KNIFE
    Publication number: 20180125520
    Abstract: A retractable knife includes a blade that is mounted on a blade mounting element, where the blade mounting element is located within and is slidably engaged with a handle. The blade is moved from a retracted to an exposed position upon pushing a button of the blade mounting element, which results in a cantilever arm bending downwards into an open space, and then pushing the element forward to move the blade outside of the protection afforded by the handle. A slit in the handle guides the movement of the blade mounting element.

  • Bucket scoop
    Patent number: 5799997
    Abstract: A scoop for removing semi-fluid materials such as joint compound from a bucket includes a handle for manipulating a receptacle. The receptacle has an open top and an open side face which conforms in shape to the arcuate sidewall of the bucket. Thus, when the receptacle is manipulated into scraping engagement with the bottom of the bucket until it engages the sidewall of the bucket, it can readily scoop up the last remaining quantity of material located within the bucket.
