I have a Visionary I as well. I didn't notice the backspacer until I read this thread. Then I took out my Visionary and inspected. Sure enough, there is a small cut o nthe backspacer. It's not as bad as yours, maybe because I usually use thumbstuds for opening and closing, instead of flicking, but it's definitely there. There's also a tiny bit of up and down blade play. Not enough to hinder use, but annoying nonetheless.
