A cutting implement including an annular blade defining a central blade aperture and a circular cutting edge. The annular blade is rotatably mounted in a handle covering a covered arc segment of the blade while allowing an outer arc segment of the blade to protrude from the handle. The device may be held through the use of a palm grip wherein some of the fingers of the user are inserted through the blade aperture and press the handle against the palm of the hand. A mechanism may be provided for selectively restraining the rotation of the blade relative to the handle.

A cookie cutter apparatus comprising: a horizontal handle, the horizontal handle having a first end, and a second end on an opposite end of the horizontal handle from the first end; a first side member attached to one end of the horizontal handle; a second side member attached to a second end of the horizontal handle; a first slide plate configured to removeably attach to the first side member and second side member, the slide plate having a first cookie cutter pattern. A cookie cutter system comprising: a horizontal handle, the horizontal handle having a first end, and a second end on the opposite end of the horizontal handle from the first end; a first side member attached to one end of the horizontal handle; a second side member attached to a second end of the horizontal handle; a lid configured to removeably attach to the first side member and the second side member; a main body, configured to removeably attach to the lid; a first slide plate configured to removeably attach to the first side member and second side member, the slide plate having a first cookie cutter pattern; a second slide plate configured to removeably attach to the first side member and second side member, the second slide plate having a second cookie cutter pattern; a third slide plate configured to removeably attach to the first side member and second side member, the third slide plate having a third cookie cutter pattern; and where the main body is configured to hold a plurality of slide plates.

A vending machine system for loading and dispensing pre-baked unpackaged food including a fixed cartridge disposed in a refrigerator of a vending machine, and a transport cartridge adapted to removably attach to the fixed cartridge, the transport cartridge operable for holding trays of unpackaged food and loading the trays of unpackaged food from the transport cartridge into the fixed cartridge, wherein, when the transport cartridge is removably attached to the fixed cartridge, a front opening of the transport cartridge aligns with a front opening of the fixed cartridge, and wherein the rack of the transport cartridge aligns with the conveyor system of the fixed cartridge such that trays of unpackaged food within the transport cartridge can simultaneously be transitioned from the rack to the conveyor system.

The pizza cutter cleaning, storage, and isolation device disclosed herein may allow a user to store and clean pizza cutters between uses, while also isolating each pizza cutter intended for specific consumers. Such a device may implement a cartridge system, one or more of which may be installed in a main body, into which a single pizza cutter may be placed. The cartridge may be designed to isolate and clean the pizza cutter installed therein, and the pizza cutters themselves may be color-coded, or the cartridges may be color-coded, so as to prevent cross-contamination of the cutters, the pizzas, or the debris picked up when cutting a pizza. The cartridges may further implement a sanitizing bath into which a pizza cutter head may be suspended, or may implement a catch tank for waste debris. The device may further comprise a blade sharpener for additional functionality.

A cake cutter includes a handle having an L-shaped blade extending therefrom. The blade includes a first section axially extending from an end of the handle and a second section perpendicularly extending from a distal end of the first section. Integrally molded with a central portion of each blade section is a raised ridge that is positioned a predetermined distance from either end of the blade section. Accordingly, the user can cut a precisely sized slice of cake or casserole by aligning the ridges with an outer edge of a cake.
