From what I heard at the Factory Sale last week was that Buck was going to do another collaboration with TOPS to produce Ron Hood's Hoodlum fixed blade. This is not a fixed blade version of the CSAR-T. From what I have heard TOPS does not make their own knives but contacts with various manufacturers to make them. Rowen Machine in Boise, ID, which makes the ESEE knives, made most of the TOPS knives in the past but is no longer doing businesss with TOPS. I'm kind of confused on how the CSAR-T is a collaboration as Buck used the frame from the Alpha/Bravo series and I cant see it as a TOPS designed knife. The Strider, Simoich, and Mayo knives were all very distinct knife models and Buck did'nt use existing production models to base them on.
