As the saying goes, "fool me once, shame on you; fool me twice, shame on me".
I'd noticed that sharp corner already and made a mental note to radius it sometime. After reading about your experience I got off my butt and decided to make the step less hazardous and repaint the frame and step which were badly in need of paint.
Honestly, sometimes I wonder if they just used one spray bomb to paint the whole frame.
Seriously, the paint is so thin I was able to strip it just by running a putty knife over it. There's definitely room for improvement in the frame painting department.
