  • Patent number: 8151678
    Abstract: A board shaped mandolin slicer includes a folding leg for stability in an angled orientation, and a “dead mans handle” for to enable exposure of the blade and adjustable thickness slicing only upon actuation of the handle. In addition, a spring resist in the handle is used in conjunction with a mechanical position guide limiting switch and angled cam which allows the user to better control the degree to which a platform move forward to expose the front of a main blade, to thus adjust the thickness of the slices uniformly. An additional child safety feature includes a pair of buttons on either side of the housing which need to be urged inwardly at the same time to unlock the mandolin slicer.
