To be honest, the most interesting part of this razor is the scales. If this wasn't a razor with scales that had a picture of Adolf Hitler and a swastika, I doubt it would have brought the price it did. To ignore the scales and the picture on them, is to ignore a very key part of what makes this item unique.
Let's take this a step further and say that the blade itself has an iron eagle and swastika etched into it. Are we to ignore that and only discuss the condition of the edge, rust, blade geometry, etc.? Not a chance. The markings on a razor help us identify it's past - even if that means it's a hoax. It's a peek into history and for me that's half the fun. Needless to say if an item has a depiction of a political figure, it's going to bring up a political topic.
I say let's let the object in question and the thoughts and feelings associated with that object lead the course of conversation. To me, it is much more fun that way.
Just my two cents. :)
