You don't need a removable wheel to sharpen a pizza cutter on a stone. That's actually pretty clear from the video showing the sharpening of the removed wheel - the fact they the wheel is not in the handle isn't material to the sharpening action.

Pizza cutters wear out by deformation of the hole in the middle of the wheel (in my experience). I have thought of hacking one to fit bearings, just for the joy of having something that is properly engineered.
