Several months ago on the Bay I say an auction for an item claiming to be a razor sharpener. It looked like a cheap contraption made out of a wire handle and some marbles. The auction was posted here by someone else and if I remember correctly it was decided that it must be some sort of scam. Well now I see this auction, only this one looks like a well made device. At this point I have to assume that these were actually used for something once upon a time. Does anyone here have any more info on what they are and if they are really meant for razors?
