Now this might be a strange kind of issue, but given that you are using a German word as a name and German is my mother tongue, I feel qualified to comment. Whilst Griffel definitely means "stylus" this meaning is out of style. The kind of stylus called Griffel has not been in use for several decades, and so next to no one uses that word in that sense. It is however still a used word, but mainly in a derogatory sense, to describe the fingers of a person. Usually when that Person touches something they should not be touching, in the worst case another Person.
