20120192435METALLIZED CUTLERY AND TABLEWARE AND METHOD THEREFOR - A plastic cutlery item molded from a plastic material, such as polystyrene, having a metallic coating that imparts to this cutlery item the appearance of metal cutlery or silverware. In one embodiment the plastic cutlery or tableware items are molded using injection molding techniques, and subjected to a vacuum metallizing process in an individualized non-contiguous manner, where a thin metallic layer is deposited on at least one of their surfaces. The resultant items simulate the appearance of metal cutlery or tableware. In one embodiment of the invention the plastic cutlery or tableware articles are molded from a clear polystyrene resin and are coated with a thin stainless steel layer through vacuum sputtering deposition on only one of the sides. The abrasion resistance of the metallic coating can be enhanced by subjecting the articles to a post-metallizing holding period or by applying a clear protective overcoat.08-02-2012

In various embodiments, the optical shaving device includes a power source that connects to one or more optical components (e.g., arranged in an array). An optic, such as a blade, can connect to and aligns with the array of optical components. The optical component(s) can provide light to the optic based on electrical energy from the power source. The optical component(s) or the optic can manipulate and direct the electromagnetic radiation to cut the hair shafts.10-09-2008
20120151777KNIFE WITH BALANCE ADJUSTMENT FEATURE - A knife is provided with a balance adjusting feature. The knife may have a blade and a handle tang. The handle has at least one balance mount, each balance mount comprising an aperture in the tang. Each balance mount is configured to accept at least one balance weight. By connecting or disconnecting weights from the balance mounts, the center of mass of the knife changes, thus permitting a user to customize the balance of the knife.06-21-2012
20090133268Grip-over knife - The present invention is a culinary knife, intended for one handed use, comprising a handle and a blade having a cutting edge as its bottom perimeter. The entire length of the handle of the knife is joined contiguously against the spine of the blade leaving no aperture between them. This joining of the handle and blade results in the user gripping onto rather than around the handle of the knife. The handle does not extend beyond the rear of the blade, thus the user grips the knife above part of the cutting edge. This provides the user the ability to apply direct downward force for cutting and provides enhanced ability to use the palm and digits to apply finely directed force and movement to the knife. Both the location of the user hand and its proximity to the blade further enhance fine control and ease of use of the knife.05-28-2009
20100175269DINING AND/OR SERVING CUTLERY MADE OF FERRITIC STAINLESS STEEL WITH A MARTENSITIC BOUNDARY LAYER - The invention relates to dining and/or serving cutlery made of a steel material which is formed from a ferritic core with an essentially martensitic boundary layer. In the dining and/or serving cutlery of the invention, the surface hardness of the boundary layer, determined according to the hardness test according to Vickers HV 3, is thereby greater by 30 to 300% than the lowest hardness of the core, likewise measured according to Vickers HV 3.07-15-2010
20120260505UTILITY KNIFE AVOIDING ACCIDENTAL DETACHMENT OF BLADE - The invention discloses a utility knife preventing its blade from accidental detachment. Prior utility knives may lose constraint on the blade due to tilting of the retaining member when the blade receives external force from the blade holder pulling outward, causing the blade to detach accidentally from the blade holder. In the present invention, the line of the action force in the engagement area of blade and retaining member extends over the axis of axle pin where the retaining member is mounted, so that when the blade receives external force pulling it outward from the blade holder, a counterclockwise torque is formed to the retaining member to allow the retaining member constrain the blade more tightly and thus prevent the blade from accidental detachment.10-18-2012
20120079723SCRAPER CHEF KNIFE - A chef knife is provided. The chef knife includes a blade and a handle. The blade has a length and a spine, wherein the spine of the blade defines a flat surface running the entire length of the blade. The spine of the blade protrudes outward from the handle, such that the spine rises above the top surface of the handle. The blade has a cutting edge, wherein the cutting edge extends below and under the handle. The blade has a depth, which depth increases from the point of the blade to the heel of the blade. Under the condition that the knife is oriented in the cutting position, the handle is angled downward with respect to the plane defined by the flat surface of the spine and the handle is angled upward with respect to the plane defined by a main portion of the cutting edge.04-05-2012
