A box lifting device places weight upon the lateral surface of lifter's forearm or hand. Preferred embodiments include a lifting body and a handle molded as a single piece of injection molded plastic, a lifting plate having metal teeth or other lifting members, and a weight transfer member that shifts the weight of a box to a lateral surface of the users forearm or hand. The lifting members are preferably angled other than 90° relative to a long axis of the handle. Preferred lifting plates include a plurality of openings, such that the lifting members of one plate enter the openings in the other plate and vice versa during storage of the devices. Magnets can be included to couple the left and right mating pairs. Lateral and medial forearm stops can be used to restrict a bending movement of the user's wrists relative to the handle.

What is claimed is: 1. A pair of devices for assisting a user in lifting a box, each device comprising: a lifting body; a handle coupled to the lifting body; and a weight transfer member coupled to the lifting body in a manner that transfers weight from the box through a contact surface of the member, to a lateral surface of a forearm or hand of the user: and a lifting plate, wherein the lifting plate is part of the lifting body, and wherein the lifting plate of a first one of the pair includes openings for receipt of a plurality of lifting members disposed on the lifting plate of a second one of the pair. 2. The devices of claim 1, wherein the contact surface measures at least 25 cm2. 3. The devices of claim 1, further comprising a cushion interposed between the contact surface and the lateral surface. 4. The devices of claim 3, wherein the cushion has a region having thickness of at least 0.5 cm. 5. The devices of claim 3, wherein the cushion is replaceable by the user. 6. The devices of claim 1, wherein the contact surface comprises a main portion, and further comprising a thumb guard that is angled relative to the main portion. 7. The devices of claim 1, wherein the contact surface comprises a main portion, and further comprising a lateral forearm stop that is angled relative to the main portion. 8. The devices of claim 7, wherein the lateral forearm stop is continuous with the main portion. 9. The devices of claim 1, wherein each device further comprises a medial forearm stop positioned to contact a medial surface of a forearm of the user. 10. The devices of claim 1, wherein each device further comprises a wrist riser positioned to contact an anterior surface of a forearm of the user. 11. The devices of claim 1, further comprising a lifting plate removably coupled to the body. 12. The devices of claim 11, wherein the lifting body extends at least 0.5 cm beyond edges of the removable lifting plate in first, second, and third directions. 13. The devices of claim 11, further comprising a plurality of lifting members extending from the lifting plate. 14. The devices of claim 13, wherein the plurality of lifting members are selected from the group consisting of punched out members and pins. 15. The devices of claim 1, further comprising a plurality of lifting members angled other than 90° relative to a long axis of the handle. 16. The devices of claim 1, further comprising one or more magnets operable to separably couple the devices. 17. The pair of device of claim 1, further comprising a sweat texture portion disposed in an area defined by the handle, the weight transfer member, and a medial forearm stop. 18. A pair of devices for assisting a user in lifting a box, each device comprising: a lifting body; a lifting, wherein the lifting plate is part of the lifting body, and wherein a plurality of lifting members extend from the lifting plate, wherein the lifting plate of a first one of the pair includes openings for receipt of a plurality of lifting members disposed on the plate of a second one of the pair; a handle coupled to the lifting body; and a first stop that restricts a bending movement of one of the user's wrists relative to the handle. 19. The devices of claim 18, further comprising a weight transfer member coupled to the lifting body in a manner that transfers weight from the box through a contact surface of the member, to a lateral surface of a forearm or hand of the user. 20. The devices of claim 19, wherein the first stop is angled relative to the weight transfer member. 21. The devices of claim 18, wherein the first stop is disposed to contact a lateral surface of a user's forearm. 22. The devices of claim 21, further comprising a second stop disposed to contact a medial surface of a user's forearm. 23.
