Patent number: 10773370Abstract: A food grade safety knife includes a safety knife blade, a handle, and a stepped region adjacent the juncture therebetween. The handle is defined by a pair of spaced apart major surfaces that include an enlarged palm portion; a flared end distal to the enlarged palm portion that anchors the safety knife blade, and a neck region intermediate between. The stepped region has a thickness greater than the enlarged palm portion. The stepped region rises in a plurality of discrete steps from the generally planar major surfaces and generally increases in thickness with increasing distance from the enlarged palm portion to a maximum thickness most nearly adjacent to the safety knife blade. At least one of the plurality of steps within the stepped region is provided with at least three generally linear segments each angularly offset from adjacent ones of the at least three generally linear segments.Type: GrantFiled: December 22, 2017Date of Patent: September 15, 2020Inventor: Ronald R.

Patent number: 7055407Abstract: A metallic housing utility knife and method for making the device with a soft over molded elastomeric cover to provide blister free comfort and slip proof safety. The cover or skin is molded into the unique structure of the housing in a fashion that results in mechanical bonds that embrace the cover on the housing. The knife includes flexible posts from the cover that project into the blade storage compartment of the housing to prevent internally stored spare blades from moving within the storage compartment. An elastomeric blade clamp integrally formed with the cover serves to restrict lateral movement of blades of varying sizes when installed in a cutting position within the knife assembly. A rear quick release latch and interlocking housing sections provide a convenient way to open and close the knife and assure that it is also secure and firmly held when locked in a safe cutting position.Type: GrantFiled: December 1, 2004Date of Patent: June 6, 2006Assignee: Allway Tools, Inc.Inventors: Donald Gringer, Yuan Fang Cheng

Patent number: 5528834Abstract: A knife has a fixed blade, a plastic base fixed to the tang of the blade, and a rugged rubber grip fixed to the plastic base. A visible portion of the plastic base extends along a back of the knife and also forms a hilt and forwardly swept guard. A visible portion of the rubber forms a grip along the bottom and sides of the handle, and also a thumb rest along the top of the handle at the guard. The handle is formed by injection molding the plastic to the tang of the blade, and thereafter injection molding the rubber to the plastic. The plastic base has features thereon for ensuring that the rubber is strongly fixed to the plastic. The base and the grip are made of strong, tough, damage-resistant materials.Type: GrantFiled: January 12, 1994Date of Patent: June 25, 1996Assignee: Buck Knives, Inc.Inventors: Brett P. Seber, Roy L.

Patent number: 4563816Abstract: Young children often find it difficult to grip and control cutlery since they lack the muscle control possessed by adults. Accordingly, the piece of cutlery described is designed to make it easy for use by a young child and comprises a handle and an operative portion such as a spoon bowl, fork prongs or pusher. The handle is generally of round, barrel-shape for easy fist-like grasping by a small child and has a relatively flattened surface adjacent the operative portion for the ball of the thumb of the child to allow gripping and control of the piece of cutlery between the ball of the thumb and the four fingers grasping the handle. The longitudinal axis of the operative portion is turned in from the longitudinal axis of the handle so that when the handle is grasped, the operative portion is turned towards the body of the user.Type: GrantFiled: June 30, 1983Date of Patent: January 14, 1986Assignee: Little People LimitedInventor: Vivienne D.

Patent number: 4380122Abstract: A piece of cutlery which is designed to assist people such as children who are unfamiliar with cutlery, how to use it effectively and correctly. The piece of cutlery has a recess in the upper surface of the handle in the region where the handle and operative portion, e.g. the knife blade or fork prongs, of the piece of cutlery join. This recess is centered on the longitudinal center line of the piece of cutlery and is of a size to accommodate and locate the tip of the user's index finger in the effective and correct position for the user of the piece of cutlery. Also it is of sufficient depth to prevent accidental displacement of the tip of the finger during normal usage of the piece of cutlery. Preferably, the handle is S-shaped when viewed from the left-hand side so that it fits snugly in the palm of a child's hand with the tip of the index finger positioned in the recess.Type: GrantFiled: September 16, 1980Date of Patent: April 19, 1983Assignee: Little People LimitedInventor: Peter C.

Patent number: 4147443Abstract: A handle for a medical instrument having a handle portion. The handle portion is fabricated from metal, preferably stainless steel, and is provided with at least one annular channel disposed completely around the handle portion. An elastomer material, preferably silicone rubber, is molded on the handle portion to completely cover the handle portion, where the elastomer material extends into and fills the channel. The elastomer material provides pressure within the channel when the medical instrument is heated during steam sterilization thereof so that the elastomer material defines a seal within the channel to prevent moisture from passing between the covered handle portion and the elastomer material. Additionally, the handle portion may be provided with holes extending therethrough which are filled with the elastomer material to additionally secure the elastomer material to the handle portion.Type: GrantFiled: July 3, 1975Date of Patent: April 3, 1979Assignee: S & S Medical Products Co., Inc.Inventor: Barry A.

Patent number: 4117593Abstract: A knife has a generally flat blade with a sharp curved lower cutting edge which terminates forwardly and rearwardly in sharp cutting ends; an upper surface of the blade opposite the cutting edge is extended upwardly and forms a stem, and a curved cross section outwardly pointed handle is connected to the stem so that maximum cutting force occurs on portions of the cutting edge nearest the rearward end of the blade. A food chopper is constructed with an upward and forward curving handle and a distal forward pointed end and a rearward proximal curved sharp end on the blade and with decreasing radii of curvature toward the rearward proximal end. A cutting knife is formed with a cutting edge of uniform radius of curvature terminating forwardly and rearwardly in distal and proximal pointed ends, with a central portion of an upper surface of the blade curving upward and rearwardly and integrally forming a stem.Type: GrantFiled: May 17, 1977Date of Patent: October 3, 1978Inventor: Dimi Piligrino
