  • Patent number: 10710264
    Abstract: A severing device and method is effective to sever a portion from a frozen slab of fish or meat. The severing device can be sized to be useful in a domestic kitchen, and can be stored in a kitchen drawer when not in use. The severing device can be an elongated severing device, having an inverted Y-shaped cross section, which provides a raised separating edge and a two legged base. The separating edge can be relatively sharp. The two legs that make up the base can likewise be sharp such that any of the three legs that make up the inverted Y shape can be used as the raised edge, by rotating the severing device. Alternately the severing device can have a triangular cross section or an inverted T-shaped cross section. Also, alternately, the severing device can comprise a stand. The stand includes a base plate supporting a holder. The holder includes a vertical wall having an elongated slot. A cleaver or knife has a blade with a sharpened edge, and a handle. The cleaver is placed edge-up into the slot.

    Abstract: A safety cutting device comprises, in an exemplary embodiment, a housing, a longitudinally movable blade positioned within the housing, and a longitudinally movable guard positioned substantially adjacent the blade. Additionally, the device provides a means for substantially preventing the blade from extending through a first end of the housing when the guard is in a retracted position, such that the blade is incapable of extending out of the housing without first extending the guard. In further embodiments, the device provides a pair of longitudinally movable guards flanking the blade and configured for selectively moving independent of one another, thereby allowing both right- and left-handed users to operate the device without having to change any settings or reconfigure the orientation of the guards or blade. In such further embodiments, the blade is substantially prevented from extending without at least one of the guards first being moved out of the retracted position.

    Abstract: An elongate blade grip is attached to the top edge of a knife blade to achieve greater cutting control and efficiency. The blade grip includes a top member and two opposing side members connected to the top member. The blade grip closely conforms to the flat shape of the knife blade so as to allow knife users to choke up on the knife, or hold the knife partly by the blade. An elongate and rounded top surface on the top member relieves pressure on the proximal phalange of the index finger, thereby reducing blisters and calluses associated with choking up. The side members of the blade grip include slip resistant surfaces where the thumb and medial phalange of the index finger are normally located when choking up on the knife.

    Abstract: A cutting tool includes an elongate handle to be grasped by a user, and an elongate blade connected to the elongate handle. The elongate blade includes a substantially linear proximal portion extending longitudinally outwardly from an end of the handle, and a curved distal portion extending in a downward and forward curve from the proximal portion and ending in a tapered tip. The linear proximal portion and curved distal portion may have about equal lengths. The linear proximal portion may have a sharpened lower edge and the curved distal portion may have sharpened upper and lower edges. In some embodiments, the elongate blade may have a length of less than about twelve inches so that the cutting tool is a knife, and in other embodiments, the elongate blade may have a length of greater than about twelve inches so that the cutting tool is a sword.

  • Patent number: 7011003
    Abstract: A large kitchen or barbecue fork and protector for preventing injuries from sharp tines of the fork and preventing food contamination from bacteria and dirt on the tines. The guard is movable on a shank of the fork from a covering relationship with the sharp pointed tines to an uncovering relationship with the sharp pointed tines. The guard is comprised of a hub portion which closely fits the shank and a cover portion which encloses the tines in the covering portion. In a first embodiment, the guard is retained on the shank at the covering and uncovered positions by a permanent magnet mounted in the guard. In a second embodiment, the guard is retained on the shank at the covering and uncovered positions by the friction of the guard on the shank.

  • Patent number: 6861903
    Abstract: Signal coupling systems are provided which enhance signal isolation and dynamic range with structures that increase bias voltages in upstream signal amplifiers to guard against transistor saturation that would otherwise increase current drain, reduce response time and possibly cause lock-up of an associated gain-control system. Dynamic range is thus enhanced because these systems can operate over an extended range of source signals. The increased bias voltages also decrease parasitic junction capacitances which increases input impedances and thereby enhances signal isolation and reduces signal distortion.

  • Patent number: 6637112
    Abstract: A deflectable safety shield extends transversely across a cutting plane in a protective guard position completely overlying the cutting edge of a utility knife. A portion of the shield extends over-center with respect to the cutting edge, thereby tending to hold the shield in the guard position in response to contact of the shield against the operator at the normal angle of engagement during follow-through that accompanies rapid slicing hand movements. The shield is resiliently biased for movement to the guard position by a torsion spring. An outwardly-turned flange portion of the shield provides an angularly offset leverage point for reacting the torsion spring when the operator desires to perform a cutting operation. The shield swings away from the cutting plane automatically in response to pressure engagement of the offset flange portion against the box surface, thus exposing the cutting edge.

  • Publication number: 20020170184
    Abstract: A control system is provided for improving the maneuverability of a handheld tool such as a knife. The apparatus of the present invention includes a control knob disposed upon the shaft or blade and spaced apart from the handle to create a finger gap. The methods of the present invention include grasping the control knob and/or grasping the finger gap while loosely cradling the tool handle. Another method includes grasping the handle and extending one or more digits of the hand beyond the hilt to grasp the control knob and/or the finger gap, while maintaining a grip on the handle. The control knob and the finger gap work together with the tool handle and the user's hand to provide improved maneuverability of the handheld tool.

  • Patent number: 6381855
    Abstract: Knife-holding assist including a blade-riding section and a grip section formed on two lateral sides of the blade-riding section. The blade-riding section has a U-shaped cross-section and includes a pair of opposite plate bodies integrally connected with each other. The plate bodies define a receiving channel, whereby a blade of the knife can be fitted into the receiving channel with the back edge of the blade abutting against the bottom of the receiving channel. The grip section includes two flat arched sections, whereby a user's hand can grip the grip section with the palm pressing an upper edge of the blade-riding section to facilitate cutting operation. The grip section also protects the fingers from slipping and getting hurt by the blade.
