  • Patent number: 5361497
    Abstract: A folding knife holder and method, whereby a folding knife can be safely carried in an elongate knife holder, comprising a housing member that has an elongate recess defined by a base surface, side surfaces and end surfaces, and sized and shaped to receive the knife in an orientation that is substantially parallel to the base surface, with the spine of the knife laying against the base. The margin of the walls of the housing member define an elongate orifice opening into the recess. The orifice is partially occluded at one end by a strike member. The strike member has a gap, wider than the knife blade. When the back of the knife blade is grasped and pulled in an outward direction, the knife blade will pass through the gap in the strike member and the strike member will blockingly engage the butt of the knife handle, thereby allowing the knife blade to be pivotably rotated into an open position.

  • Patent number: 5347714
    Abstract: A razor head comprises a body portion defining a guard and a cap, and a blade assembly having a blade disposed therein. The blade assembly is mounted by a first and second mounting member to the body portion in relation to the guard and cap in a manner to comprise a four-bar linkage. The body portion defines a stationary member of the four-bar linkage. The first and second mounting members each have one end connected to the body portion in a manner to define rotational members of the four-bar linkage about a separate axis of rotation for each of the first and second mounting members. The blade assembly is connected to the other end of the first and second mounting members to define a movable four-bar member responsive to rotational movement of the first and second mounting members so that shaving forces acting upon the blade assembly cause the blade assembly to move relative to the body portion.
