Abstract: A hand tool has first and second tool legs that are connected in a pivot region and which overlap in an overlapping region both in an open state of the hand tool and in a closed state of the hand tool. The tool legs interact with a spring such that the tool legs can be pivoted, even beyond a basic open position, into an extended open position by the user in applying manual force against the force of the spring, the spring coming into action in the case of the additional pivot movement of the hand tool legs beyond the basic open position and/or in the case of a closing pivoting movement of the hand tool legs acts on different bearing surfaces of the hand tool legs.

Abstract: A pin cutoff tool employs shears to sever pins. The pin cutoff tool is formed in a pliers-like configuration, with working surfaces formed within the jaws, and a pair of handles situated in working arrangement opposite a pivot point to provide leveraging advantage to the shearing surfaces. Stops may be formed within the jaws to limit the amount of closing travel, and to limit the amount of opening travel. The closing stops also may be formed such that, when closed, the inner surfaces of the jaws are substantially equal to the width of a pin being cut. Grooves may be formed in the jaws to accommodate neighboring, closely situated pins, and the jaws may be relatively narrow, so that neighboring pins in a direction orthogonal to the axis of the channels are not disturbed by the tool when shearing a pin.

Abstract: An air bag buffer device for a hand tool comprises a hollow bag and a plug. The front end of the hollow bag is a hollow and sealed snake-like tube. At the center of one end of the snake-like tube is formed with a round post. The center of the round post has an axial helical hole, and the helical hole is communicated with the interior of the snake-like tube. The plug is formed as a helical post, the center of which is an axial air hole, the front end of the air hole formed with a unidirectional elastic valve piece which is closed in the front end. Thereby, the front end of the plug is screwedly inserted into the helical hole of the round post of the hollow bag so that the buffer device is firmly secured to one handle or two handles of a hand tool. As the hand tool applies a force, the impact from closing two handles are reduced to resist the opening of the two handles for being used again.

Abstract: A hand-actuated scissors useable by an individual whose hands and fingers are weak or impaired and therefore experience difficulty in operating a conventional scissors. The scissors include a pair of blades whose cutting edges face each other, the blades being joined by a swivel pin whereby in an open state of the scissors the blades are angled with respect to each other. When the scissors are put into a closed state, the blades are then brought together to effect a cutting action. The handle sections of the blades which extend beyond the swivel pin are so shaped that in the open state the ends of these sections are widely spaced apart. Bridging the ends of the handle sections is a yoke defined by a saddle-shaped plate of resilient material forming a spring-loaded grip which normally maintain the scissors in an open state.

Abstract: A scissors construction is disclosed including a first and second member pivotally mounted with respect to one another with conventional blade means being adjacent. A movably mounted thumb loop means is included interconnected with respect to the handle of the second member by way of a ball and socket interconnection allowing free movement longitudinally along and perpendicularly around the axis of the second handle. Also, a tab means is included to limit the rotational movement of the thumb means about the ball within the socket itself. A telescoping slide means is biased into contact with a slot defined therein extending circumferentially around the handle means and across the neck of the ball when positioned within the socket to thereby secure the ball therein in a movable fashion as described above.

Abstract: A tool for applying compression, e.g., a nutcracker, having a hinged pair of lever arms pin connected to a common housing. The housing contains a stopping device designed to provide a fixed crushing rotation movement to crush the nutshell without crushing the nutmeat. Furthermore, when a nut or other workpiece is not inserted in the tool, the lever arms are free to move, without restraint, making insertion of the nut a convenient and random action. From the standpoint of the user, the nutcracker will look like and operate exactly like the majority of nutcrackers in use today. The major difference is the stopping action, which will prevent damage to the nutmeat and allow less fragmented crushing of the nut shell.

Abstract: A pruning shear with offset cutting blade is disclosed which includes in combination a pair of pivotally interacting blades which are capable of closing upon one another to sever a twig or small branch. A first blade is designed as a cutting blade having one side ground to form a gradually sloped first bevel. A more sharply sloped second bevel angularly intersects the first bevel to define an offset cutting edge. The second blade is provided with a pair of laterally spaced support anvils, which anvils define a clearance space to receive therein at least the cutting portions of the cutting blade. The cutting edge of the pruning shear cutting blade is pivotally movable into the clearance space in a manner to always position the cutting edge in spaced relationship to each of the support anvils.

The pivotal portions are provided one each with control portions for regulating the rotation of the blades and also provided on the end faces thereof unconnected relative to the handles one each with segmental surfaces of circles with the pivotal holes as their respective centers adapted to draw a continuous arc when the blades are opened. It is safely used as scissors without pinching fingers etc. between the ricassos and, in its closed state, advantageously used as a paper knife.

Abstract: First and second metal blades made from uniform thickness stock are fashioned into scissors which may be disposable suture scissors. Each of the blades is stamped from sheet metal, they are pivoted together, and handles extend in the opposite direction from cutting edges on the blades. Resilient means is provided by the handles being resilient and stop means are provided to limit the closed position of the cutting edges to prevent overriding, namely overclosing, of the cutting edges. The stop means includes first and second stop surfaces integral with the first and second blades, respectively. The stop surfaces are close to the pivot relative to the length of the handles, the blades have only frictional opposition to movement until the stop surfaces engage, and then the subsequent stressing of the resilient means establishes a cushioned stop of movement of the handles without any further movement of the cutting edges past the fully closed condition.
