  • Patent number: 5426855
    Abstract: An improved safety utility knife has a hollow handle and a blade which is normally retracted within the handle, but can be extended by squeezing an operating lever. The lever is connected to the blade holder by a toggle linkage having a rearmost pin secured in a discrete support whose position is adjustable. A thumbscrew threaded into the support enables one to adjust the position of the support from outside the handle, and thus change how far the blade protrudes from the handle when the operating lever is fully depressed.

  • Patent number: 5282316
    Abstract: The invention provides a hand held razor-containing cutting device formed from two separable halves that are connected together during use along a centrally located longitudinally extending parting line. The two halves of the tool are held in contact with one another by means of frictional connecting elements that allow the halves of the tool to snap together for use. A pair of adjacent disassembly tabs are provided. One such tab is located on each half of the tool to facilitate separating the halves of the tool by prying the halves apart, usually with a screwdriver or similar tool that is placed between the tabs and then twisted to pry the tabs away from one another for separating the two portions of the cutting device so that the razor blade can be removed and replaced when required. The frictional connecting elements comprise C-shaped cooperating retaining studs that extend from one half of the tool and during assembly snap into openings provided in the other half.
