Bob

Bob is Vibeke's Tikari. It's a Carlin knife that turns into a ladybug.
== Spoilers ==
Bob was deactivated when Mishka broke Vibeke's Tikari link. She managed to use Bob's dead knife body to kill Mishka's brother and destroy Mishka's eye. After that she was happy to have a new Bob made, and she wields Bob 2 for the rest of the series.
