| 20090133268 | Grip-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 |

| 20120192435 | METALLIZED 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 |
| 20120260505 | UTILITY 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 |
| 20130025134 | POWER OPERATED ROTARY KNIFE - A rolling bearing strip for a power operated rotary knife providing bearing support for rotation of a rotary knife blade with respect to a blade housing.

| 20150075008 | SELF-STANDING HYGIENIC SAFETY KITCHEN KNIFE - The present invention relates to a kitchen knife for trimming food ingredients in a kitchen or galley, and more particularly, relates to a self-standing hygienic safety kitchen knife which is adapted to be able to maintain a hygienic state when the knife is placed on a chopping board or sink, by ensuring that the knife blade portion is separated from the deck such that extraneous material does not stick to the knife blade for trimming the food ingredients and such that water on the knife blade falls towards a ground surface. The self standing hygiene kitchen knife of the present invention is a kitchen knife having a handle, wherein the handle is formed so as to have a circular cross section, and the centre of gravity of the handle is formed in the lower part of the handle in the knife-blade direction, and where the knife blade is concerned, the knife blade is constituted spaced a predetermined distance inwards from the outer surface of the handle. | 03-19-2015 |
| 20150328781 | KITCHEN KNIFE DEVICE - A kitchen knife device designed to cut food includes a handle and a blade connected to an end of the handle. The blade has two opposite lateral surfaces, on each of which a plurality of recesses is formed and arranged side-by-side in a row. The recesses formed on the two lateral surfaces of the blade are symmetrical in position. Due to air existing in the recesses, food being cut with the kitchen knife device does not easily stick to the lateral surfaces of the blade, and a user needs not to take time to separate the split food from the lateral surfaces of the blade, making the cutting more efficiently. | 11-19-2015 |
