A hand tool support device includes an attachment bracket, at least one armband, at least one transfer rod, and a flexible connector. The attachment bracket is configured to be attached to a hand tool body of a powered hand tool having a hand tool grip configured to be held by a user. The hand tool body has a tool bit rotatable about and/or reciprocative along a tool axis. The armband is configured to receive a forearm of the user. The armband has an armband axis. The transfer rod extends between and couples the armband to the attachment bracket. The flexible connector is included at a lengthwise location of the transfer rod and enables movement of the armband axis relative to the attachment bracket, and absorbs at least one of torque, vibration, and shock on the gripping hand, wrist, and forearm of the user.

The hand tool support device of claim 1, wherein: the attachment bracket includes a bracket liner comprising a resiliently compressible material lining at least a portion of an inner surface of the attachment bracket. 8. The hand tool support device of claim 1, wherein: the attachment bracket includes an outer surface having a lip protruding laterally outwardly from the outer surface. 9. The hand tool support device of claim 1, wherein: the attachment bracket comprises a first bracket portion and a second bracket portion configured to be fastened to each other in a manner such that the hand tool body is clamped therebetween. 10. A hand tool support device for a powered hand tool, comprising: an attachment bracket configured to be attached to a hand tool body of a powered hand tool having a hand tool grip extending outwardly from the hand tool body, the hand tool grip configured to be held by a user, the hand tool body having a tool bit being at least one of rotatable about and reciprocative along a tool axis, the attachment bracket configured to be coupled to, attached to, or clamped to the hand tool body in a manner such that the attachment bracket surrounds the tool axis;a proximal armband located nearest the attachment bracket and a distal armband located furthest from the attachment bracket, the proximal armband and the distal armband interconnected by one or more connecting rods;a pair of transfer rods arranged in laterally-spaced relation to each other and coupling the proximal armband to the attachment bracket; anda pair of flexible connectors respectively included with the pair of transfer rods and coupling the transfer rods to the attachment bracket. 11. A method of supporting a powered hand tool, comprising: holding, with a gripping hand of a forearm of a user, a hand tool grip of a hand tool body of a powered hand tool having a tool bit at least one of rotatable about and reciprocative along a tool axis of the tool bit;engaging the forearm to at least one armband of a hand tool support device having at least one transfer rod extending from the armband to an attachment bracket coupled to, attached to, or clamped to the hand tool body in a manner such that the attachment bracket surrounds the tool axis; andsupporting, using the forearm engaged to the armband, a portion of a weight of the powered hand tool. 12. The method of claim 11, wherein the hand tool support device includes a flexible connector at a lengthwise location of the transfer rod, the method further including: operating the powered hand tool to cause at least one of rotation and reciprocation of the tool bit; andabsorbing, at the flexible connector, at least one of torque, vibration, and shock generated during at least one of rotation and reciprocation of the tool bit. 13. The method of claim 11, wherein the step of engaging the forearm to at least one armband comprises: engaging the forearm to a proximal armband located nearest the attachment bracket; andengaging the forearm to a distal armband located furthest from the attachment bracket and axially spaced apart from the proximal armband along an armband axis, the proximal armband and the distal armband interconnected by one or more connecting rods. 14. The method of claim 13, wherein the steps of engaging the forearm to the proximal armband and the distal armband comprise: bearing, against the proximal armband, a side of the forearm on a same side as a thumb of the gripping hand; andbearing, against the distal armband, a side of the forearm opposite the thumb. 15. The method of claim 11, wherein the armband has an open cross section, the method including: securing the armband to the forearm using a strap. 16. The method of claim 11, further including: attaching the attachment bracket to the hand tool body prior to holding the hand tool grip of the powered hand tool and engaging the forearm to the armband of the hand tool support device. 17. The method of claim 16, wherein the step of attaching the attachment bracket to the hand tool body comprises: clamping the hand tool body between a first bracket portion and a second bracket portion fastened to each other. 18. The method of claim 11, further including: absorbing, during operation of the powered hand tool, at least one of torque, shock, and vibration using a resiliently compressible material lining at least a portion of an inner surface of the attachment bracket in contact with an exterior surface of the hand tool body. 19.
