Probably hand honed with the accusharp knife sharpener listed below it Atleast the 100$ replicas look really cool.
I personally like how they say it is 'functional'. Why does that sound like a lawsuit waiting to happen.
It's even better when you read the review. 2 of the 7 say that the razor is functional to shave with. Perhaps the scarriest review was "Looks really good, i bought one for me and my little sister, and im still waiting for it, it looks hella fun" Really, what could possibly go wrong???
