  • Patent number: 9138106
    Abstract: An improved pressure cooker design including a two-piece handle utilizing a common connection point to a cover to increase resistance to damage due to over tightening of connecting screws while simultaneously allowing the use of a conventional handle size with a reduction in overall packaging size. The two-piece handle design includes a cover base portion and a cover grip portion wherein a pair of nuts are mounted within the cover base portion to receive coupling screws at both ends of the nuts for joining the cover and the cover grip portion to the cover base portion. Tightening of the coupling screws provides for continuous metal on metal contact eliminating damage to weaker polymeric materials while allowing a consumer to quickly and easily attach the cover grip portion of the two-piece handle to the cover base portion at a point of use so as reduce overall packaging dimensions.

  • Patent number: 9138850
    Abstract: A motorized knife sharpener and related methods of sharpening knives, wherein the knife sharpener is capable of sharpening knives of varying types and styles. The motorized knife sharpener includes a housing, motorized grinding assembly and an adjustable blade guide assembly. The adjustable blade guide assembly includes a selector switch accessible to a user on a front portion of the housing. With the selector switch, the user is able to selectively adjust a presentation angle defined by a blade guide relative to a grinding wheel. The selector switch is operably coupled to the blade guide with a cam assembly that pivots the blade guide with respect to the grinding wheel so as to vary the blade presentation angle.
