The intelligent design of wheelbarrows greatly reduce the force required to move heavy loads. But the incumbent design of the handles, unchanged since the object's inception, fails the user when it comes time to dump.

When pushing a wheelbarrow up onto its nose, the angle of the handles places stress on the wrists, before eventually overcoming the limits of the joints altogether; at this point the user must awkwardly transition their grip, at the precise moment that the load is growing perilous.

To solve this, acompany called Pivot-All Motion Tools has come up with a clever design for wheelbarrow handles that pivot.

These allow you to maintain the same neutral wrist posture throughout the entirety of the dumping motion.

The company has licensed the design to Milwaukee and other manufacturers. (Hence the disparity between the company's name, Pivot-All, and the "Pivot-Haul" you see in the video above.) They also sell their own version for $70.
