Some RATs are available from RAT. All are available from dealers, I've bought from KnifeWorks, other's: New Graham....etc look at the RAT website. I know of no blades in D2 as of now, but someone else with more knowledge will chime in, I'm sure. The RC-3s and RC-4s will have the OD/Orange (waiting myself for the RC-4). Also coming out: RC-6, RC-5 SERE (about 2 months), IZULA (about a month). Stick around and let us know which RAT you get.
