lo everybody!

I just became a member here only to ask u a question about a small razor found on german ebay yesterday.
It says it's size is about 31 mm !!!
Is there a razor of this size?
Do you think this might be a fake?....coz I think the photos look pretty real!
Never ever heard about razors of THIS size

...don't know if it's allowed to post links to ebay...so I better won't
