Someone needs to buy this before I do!

As it is I think I will pass, because I can't put a cheater on it, and it seems a little on the short side to achieve the required torque to bust loose a 5-1/2" bolt by hand.
It is hard to imagine that thing actually being useful in the real world, so it must have been a promotional piece of some sort.
No real use for it. Plus I wouldn't want to use it being open ended, it may round off the nut/bolt, only closed 12pt wrenches for me. 
Take a peek at Ingersoll rand's 2 1/2" drive impact
I want to see it in full impacting operation.
