The walking cane of claim 1, wherein the cane is moved back to the locked configuration by sliding the sleeve and the external tubing in a distal direction on the structural support tubing to move the internal rod proximally to retract the spring loaded trigger and activate the grasper actuator to retract the two proximal phalanges and the two ligaments inwardly in a substantially aligned and parallel position with each other, wherein the two distal phalanges and the two half boots retract inwardly towards the cane axis in a substantially aligned and parallel position with each other while remaining parallel to each other and the structural support tubing;wherein as the sleeve and external tubing are fully extended in a distal direction, the external tubing covers the two proximal phalanges, the two ligaments and the two distal phalanges in a substantially straight position that is substantially parallel with each other and the structural support tubing, and the complementary internal faces of the two half boots are joined so as to form the ground contact end for the cane. 3. The walking cane of claim 1, further comprising a skid-resistant surface on the ground contact end of the cane. 4. The walking cane of claim 1, further comprising a plurality of complementary ridges on the internal faces of the two half boots. 5. The walking cane of claim 1, wherein the trigger comprises a non-slip gripping surface. 6. A combination cane and grabber tool comprising: an elongated cane body comprising a structural support tubing having a cane axis, a proximal end and a distal end;a handle on the proximal end of the cane, the handle including a trigger;a concealable grasper on a distal end of the cane, wherein the grasper comprises an actuator, a wrist, a first proximal phalange, a first ligament, a first distal phalange, a first half boot, a second proximal phalange, a second ligament, a second distal phalange, a second half boot;an internal rod operatively attached to the trigger, wherein the internal rod extends from the trigger on a proximal end and is operatively attached to actuator on a distal end;a sleeve and a distal external tubing on the structural support tubing, wherein the sleeve and the external tubing are configured to slide proximally to unlock the grasper for grasping objects;wherein in a closed position of the cane and grabber tool, the sleeve and the external tubing are detained in a distal position, further wherein the first proximal phalange, the first ligament, the first distal phalange, the second proximal phalange, the second ligament, and the second distal phalange are all covered by the external tubing in a substantially straight position that is substantially parallel with the structural support tubing, further wherein the first and second half boots each have an internal face that are complementary to each other, and are joined to form the ground support end for the cane;wherein an unlocked position of the cane and grabber tool is achieved by sliding the sleeve and the external tubing in the proximal direction, which uncovers the first proximal phalange, the first ligament, the first distal phalange, the second proximal phalange, the second ligament, and the second distal phalange; wherein the internal rod is moved in a proximal direction to allow the actuator to open the grasper by rotating the first proximal phalange and the first ligament outwardly away from the cane axis in a substantially parallel position with each other, and rotating the second proximal phalange and the second ligament outwardly away from the cane axis in a substantially parallel position with each other, wherein the first proximal phalange and the first ligament extend outwardly in a direction that is opposite to the outward direction of the second proximal phalange and the second ligament, wherein the distal movement of the internal rod also rotates the trigger away from the handle;wherein in a grasping position of the cane and grabber tool, the trigger is pulled towards the handle with force, pulling the internal rod in the proximal direction, which activates the actuator to rotate the first proximal phalange and the first ligament inwardly towards the cane axis in a substantially parallel direction with each other, and rotates the second proximal phalange and the second ligament inwardly towards the cane axis in a substantially parallel direction with each other, wherein the first proximal phalange and the first ligament rotate inwardly in a direction that is substantially aligned and opposite to the inward direction of the second proximal phalange and the second ligament thereby closing the grasper; andwherein the first distal phalange and the first half boot move inwardly towards the cane axis, and the second distal phalange and the second half boot move inwardly towards the cane axis, in parallel to each other motion and parallel to the cane axis. 7. A lightweight walking cane with a concealable grasper comprising: a top handle, the handle including a spring loaded trigger;the concealable grasper on a distal end of the cane, wherein the grasper comprises, a grasper actuator, two proximal phalanges, two distal phalanges, and two half boots;an internal rod operatively attached to the spring loaded trigger, wherein the internal rod extends from the spring loaded trigger on a proximal end and is operatively attached to the grasper actuator on a distal end;a structural support tubing about the internal rod and extending from the handle to the grasper;a slidable sleeve on the structural support tubing;a slidable external tubing attached about the structural support tubing and extends to the grasper;wherein in a closed configuration of the cane, the external tubing covers the two proximal phalanges and the two distal phalanges in a substantially straight position that is substantially parallel with each other and the structural support tubing, and the two half boots are joined so as to form a ground contact end for the cane;wherein sliding the sleeve and the external tubing in a proximal direction on the structural support tubing uncovers the two proximal phalanges and the two distal phalanges, and moves the proximal end of the internal rod away from the spring loaded trigger, releasing the spring loaded trigger and rotating the two proximal phalanges outwardly away from the cane axis in a substantially aligned and parallel position with each other,further wherein the two distal phalanges and the two half boots extend outwardly away from the cane axis, wherein the two distal phalanges and the two half boots move outwardly in a substantially aligned and parallel position with each other while remaining parallel with the structural support tubing to form an unlocked configuration of the cane with an open grasper;wherein in the unlocked configuration, applying a force to pull the spring loaded trigger towards the handle moves the internal rod to activate the grasper actuator and retract the two proximal phalanges inwardly in a substantially aligned and parallel position with each other; andwherein the two distal phalanges and the two half boots retract inwardly towards the cane axis in a substantially aligned and parallel position with each other while remaining parallel to each other and the structural support tubing to grasp an object.
