No, you are not doing it incorrectly. The illusion is not even obvious unless you are using a spot source as your dovetailing work light. With even illumination, the highlights down the back of the saw don't look like an aris, and you are forced to look at the teeth instead of the back for alignment. In my case, I've always had a spotlight and learned precision sawing of dovetails with the L-N Independence saw, so I got hooked on using the machined bevels on the brass back for alignment, and it is now difficult to stop looking at them. I think I am getting good enough at it now (and I have accepted the purely structural nature of non-Krenovian dovetails) that I don't need that crutch. But it is still distracting.
