Nothing at all wrong with the OP knife.
Most of the PocketEze knives will have the backs of the blades truly flush with the frame.
I actually have no idea how they accomplished that, but if it was a near final task on a grinding wheel after the knife was assembled, I can see how the guy might not finish it out as required.
All of the senators and pens that I’be seen have been flush. When I do see a blade above the frame, it’s generally been a jack.
