I'm not sure if D-2E steel has made it to the Carnivore just yet. I seem to remember Bob Brothers listing the order in which the models were suppose to get D-2E. I do know that it is suppose to be available on all the models, eventually. I hope Christina or Bob answers that question, since I'm interested myself.
Talonite is a Cobalt Alloy related to Stellite, if you do a search over on the general forum there is more infomation than I can give you. The one thing that I know for sure is a Talonite or Stellite blade will never rust! Can't happen ever, no steel is in either material to rust.
