I forgot to ask.

Has anyone seen one like this? Is it a mistake? I thought maybe someone forgot to grind one side, but it doesn't look like that, it looks more like a hollow ground razor was re-ground flat.

or maybe this is a legitimate style of wedge? Is this a 1/2 wedge?????

Or maybe it is some kind of display razor, and the back side was not supposed to show?

Should I go ahead and put a bevel in the other side and try shaving with it, or is it like one of those double-stamped pennies that is worth more because it is a rare defect?

Any info appreciated.
