BC Rich Warlock fret question

[Evlrpr]

I am trying to find out if this bass with neck frets that are shark teeth design with point facing body are custom or is this a r&d from BC Rich and if so, what are years they did this? It is a white warlock from Class Axe in LA is all I have been able to find. Any help would be appreciatted. I just put in a set of Geezer Butler EMG's and it rocks hard with no diastortion!
