I've heard someone say they had "Razorback" too, but I later found out the guy had no clue what he was talking about. He told me that Razors Edge came from 'Razorback". He also told me that his dog had Gator, Colby, Razors Edge, Jeep, and the dog ended up only having some TnT and Sorrells and the rest was scatter bred with no Gator, Colby, Razors Edge, or Jeep. So, I don't know if it's real or not. Good luck trying to find it.
