Actually, Chris has made a couple of attempts at collaborations, but they haven't turned out to be very popular. The Fantoni Razionale was a pretty decent folder and the Gerber LHR was a decent fixed blade. Personally, I think that Chris missed an opportunity that other popular high-end makers have capitalized on by not collaborating on more high-quality, lower-cost production models. Rick Hinderer has done it right by maintaing controlling interest in his designs and choosing a manufacturing house (KAI) that can consistently produce models that don't denigrate his brand. Others have also done this to some extent, but you have to make sure the production house is top-notch. Anything less and it becomes a joke. The opposite end of this spectrum would be the release of a very limited number of full customs by Chris. Can you imagine a current model "H" Sebenza?
Think about it - a fully-endorsed Chris Reeve collaboration with, say, Spyderco or Zero Tolerance (forget about the Spydie-hole for now) for around $200, typical CRK-produced Sebenzas for $450, and fully handmade Sebenzas for $1000+/-. We wouldn't be worrying about the 25 Micarta inlays then, would we?
