There is an RV-6 on my field with the same handle, looks pretty cool.
He built his plane in texas with the help of some friends. He is a retired airline pilot and one of his helper buddies was an airplane metal guy, hence the neet nicety of the handle.
My -6 is pretty easy to push around, mostly at the fuel pump, because when I'm at the hangar, I have the towbar, but I do have to place myhands flat on ribs etc and get my prints all over a nice wax job.
BTW, I really love the full swivel tail wheel, I originally had the standard wheel and chains and it was a pain to roll back.
