Patent number: 11203127Abstract: 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.Type: GrantFiled: May 23, 2003Date of Patent: December 21, 2021Inventors: Randall Cornfield, Miodrag Jankovic

Patent number: 7930804Abstract: An implement handle graspable by a hand of an intended user and connectable to an implement head includes a generally elongated body defining a body longitudinal axis, a body forward end for connection to the implement head and a longitudinally opposed body rearward end. The body also defines a body top surface and a substantially opposed body bottom surface. The body is configured so as to define a longitudinal cross-sectional configuration having a substantially fusiform encirclable section tapering rearwards towards the body rearward end and forwardly towards a neck section. The neck section diverges forwardly into an abutment section. The neck and abutment sections together define a thump rest area on the body top surface and an index rest area on the body bottom surface. The abutment section tapers forwardly into a spacing section for spacing the fingers of the intended user from the implement head.Type: GrantFiled: December 30, 2003Date of Patent: April 26, 2011Inventor: Randall Cornfield

Patent number: 7252255Abstract: An implement for supporting foodstuff and allowing food preparation operations to be performed thereon. The implement includes a body having a substantially planar working surface. The working surface includes a main area and at least one substantially coplanar auxiliary area. The auxiliary area has at least a protruding portion thereof protruding integrally and outwardly from the main area. The auxiliary area has a geometrical configuration distinct from that of the main area so as to facilitate visual identification thereof and visual differentiation thereof from the main area. The main and auxiliary areas are adapted to improve the cognitive ergonomicity of the implement by facilitating the delimitation of distinct coplanar and adjacent working areas for performing corresponding distinct food preparation operations. The implement includes a discharge aperture extending therethrough and a plurality of adaptors connectable thereto for performing various culinary operations.Type: GrantFiled: August 22, 2003Date of Patent: August 7, 2007Inventor: Randall Cornfield
