Karen Walker's pseudonym from Will & Grace. She's certainly a character who appears proper but would have wrist blades.
Actually, I like Ada Lovelace.
EDIT: or possibly Spong von Stoom (or Stoom von Spong). Nice alliteration and the words possibly became "Punk of Steam" (or "Steam of Punk"). Also possible, and I like better, is Catamite von Stoom.
Sadly, this seems to have been more obscure then I thought.
Augusta Ada King, Countess of Lovelace was a real person born in 1815 and who died in 1852. The daughter of Lord Byron, she was a writer, mathematician, associate of Charles Babbage, Charles Dickens and many of the important scientists of the day, and she was the world's first computer programmer.
