1. A pick up device for grasping an object, the device comprising: a) a head region comprising two opposing angled jaw members;b) a tube region operably connected to the head region wherein the tube comprises a cable; and,c) a handle region operably connected to the tube region, which handle region
1. A pick up device for grasping an object, the device comprising: a) a head region comprising two opposing angled jaw members;b) a tube region operably connected to the head region wherein the tube comprises a cable; and,c) a handle region operably connected to the tube region, which handle region comprises a handle body having a base, a trigger, and a hinged linkage lever, which hinged linkage lever has a free end and wherein the hinged linkage lever comprises an upper linkage arm, a lower linkage arm, and a hinge connecting the two arms;wherein the cable is operably connected to the free end of the hinged linkage lever at a first end of the cable and is operably connected to the jaw members at a second end of the cable; and,wherein squeezing the trigger causes the hinged linkage lever to extend in the handle body towards the base of the handle body thus causing the cable to move proximally in the handle body and in the tube region, which movement causes the opposing jaw members to move towards one another. 2. The device of claim 1, wherein the jaw members comprise a textured inner surface layer. 3. The device of claim 1, wherein each jaw member comprises a pad area at its proximal tip. 4. The device of claim 1, wherein the movement of the trigger causes a movement of the jaw members over a greater distance than that moved by the trigger. 5. The device of claim 1, wherein the handle body comprises a palm rest area, which palm rest area comprises one or more of a thermoplastic rubber or a thermoplastic elastomer overlay on the handle body. 6. The device of claim 1, wherein the head region can be rotated in relation to the tube region, and secured in one or more orientations. 7. The device of claim 1, wherein each of which jaw members comprises a proximal end and a distal end, and each of which jaw members is operably attached at a pivot point to a jaw base assembly, thus allowing movement of each jaw member around its pivot point; wherein the proximal end of both jaw members operably interacts with a jaw actuator within the jaw base assembly, which said jaw actuator is operably connected to an actuator rod and a jaw actuator spring;wherein the tube region comprises an elongated hollow tube enclosing the cable, and wherein the cable is operably attached to the jaw actuator rod; and,wherein squeezing the trigger causes the hinged linkage lever to extend in the handle body towards the base of the handle body, thus causing the cable to move proximally in the handle body and in the tube region and causing the jaw actuator rod and the jaw actuator to move proximally, which in turn, draws in the proximal end of each jaw member, thus causing each jaw member to move around its pivot point and causing the distal ends of the opposing jaw members to move towards one another. 8. A method of grasping or picking up an object, the method comprising: a) situating two opposing angled jaw members of a device around the object, each of which jaw members comprises a proximal end and a distal end, and each of which jaw members is operably attached at a pivot point to a jaw base assembly, which allows movement of each jaw member around its pivot point; wherein the proximal end of both jaw members operably interacts with a jaw actuator within the jaw base assembly, and which said jaw actuator is operably connected to an actuator rod; the device also comprising an elongated hollow tube region, enclosing a cable, which said cable is operably connected to the actuator rod; the device also comprising a handle region comprising a handle body having a base, a trigger, and a hinged linkage lever, which hinged linkage level has a free end and wherein the hinged linkage lever comprises an upper linkage arm, a lower linkage arm, and a hinge connecting the two arms, and, wherein the cable is operably coupled to the free end of the hinged linkage lever; and,b) squeezing the trigger causing the hinged linkage lever to extend in the handle body towards the base of the handle body thus causing the cable to move proximally, and causing the jaw actuator rod and jaw actuator to move proximally, and in turn, drawing in the proximal end of each jaw member, thus causing each jaw member to move around its pivot point and causing the distal ends of the opposing jaw members to move towards one another and thus grasp or pick up the object. 9. A method of grasping an object, the method comprising situating two opposing jaw members of a device around the object, which jaw members are operably attached to a cable, which cable is also operably attached a hinged linkage lever wherein the hinged linkage lever comprises an upper linkage arm, a lower linkage arm, and a hinge connecting the two arms; and, squeezing a trigger of the device, which squeezing causes the hinged linkage lever to extend and which hinged linkage lever is operably coupled to the opposing jaw members via the cable; thereby moving the jaw members towards one another and grasping the object. 10. A pick up device for grasping an object, the device comprising: a) a head region comprising two opposing angled jaw members, each of which jaw members comprises a proximal end and a distal end, and each of which jaw members is operably attached at a pivot point to a jaw base assembly, thus allowing movement of each jaw member around its pivot point; wherein the proximal end of both jaw members operably interacts with a jaw actuator within the jaw base assembly, which said jaw actuator is operably connected to an actuator rod and a jaw actuator spring;b) a tube region comprising an elongated hollow tube enclosing a cable, which said cable is operably connected to the actuator rod; and,c) a handle region comprising a handle body having a base, a trigger, and a hinged linkage lever, which hinged linkage lever has a free end, and wherein the hinged linkage lever comprises an upper linkage arm, a lower linkage arm, and a hinge connecting the two arms, and, wherein the cable is operably coupled to the free end of the hinged linkage lever;wherein squeezing the trigger causes the hinged linkage lever to extend in the handle body towards the base of the handle body thus causing the cable to move proximally in the handle body and in the tube region, which movement causes the jaw actuator rod and the jaw actuator to move proximally, which in turn, draws in the proximal end of each jaw member, thus causing each jaw member to move around its pivot point and causing the distal ends of the opposing jaw members to move towards one another. 11. The device of claim 7 or 10, wherein the jaw actuator spring exerts pressure against the proximal end of the jaw actuator which causes the distal ends of the jaw members to pivot away from each other as the jaw actuator is pushed distally. 12. The device of claim 7 or 10, further comprising a latch mechanism, wherein the latch mechanism comprises a spring loaded latch operably attached to a latch cable that is operably coupled to a latching lever, which latch mechanism when engaged, reversibly locks the trigger, thereby reversibly locking the jaw members at a desired position. 13. The device of claim 12, wherein the device further comprises a cable spring enclosed within the tube region and which cable spring is operably connected to the cable and to the actuator rod and wherein expansion of the cable spring allows the trigger to be squeezed further in even when the jaw members cannot move closer together, thus allowing the trigger to move far enough into the handle body so that if the latching lever is set, the spring loaded latch will engage and prevent the jaw members from opening.
