Dovo Facharbeit

[Photographerid]

Hi,
I'm new to the wet shaving world. I bought my first razor (a Henckels 50) from whippeddog. I can shave fairly well, although I still need to improve my technique.
I recently saw a seller in my local online shop who sell a Dovo. The blade is written Dovo Facharbeit. I attach the picture below. Is it counterfeit? (Is there even a Dovo counterfeit, btw?) I'd like to buy this one, but i'm still hesitated.



Thanks in advance.
