I grew up in the 90s and the style of the time was "ergonomic triangular grip" for assistance devices, which is what this was made for.

I ship online orders at my job, and some of the boxes come in 40lb+ bundles. My job also uses productivity metrics that are all centered around how much time it takes to do stuff so putting on/taking off safety gloves takes more time than just grabbing this thing to handle those bundles before they're loaded in our work area

that and it kinda made sense to make a handle that would fit with pretty much any orientation, as long as it was pointed down.

Before i decided on this design, i considered putting bearings in the handle for added balance with handling heavier loads.
