I can't believe I missed this thread considering my interest in the Dieter series MOD blades. You have yourself an early MOD CQD MKI before they added the glass breaker. The very cool thing about your knife is the matte clip is most likely factory, which is really rare. I've probably seen two MOD CQD MKI's with matte clips in my life (yours, and the one on my rare Damascus model). I thought maybe they used the matte clips for the early matte gray blade versions to get the finish to match but even those examples I've seen around the web have black clips. I haven't found a pattern in matte clip usage aside from limited use early on in production.
It's funny, I remember when the glass breaker versions came out, the non-breaker versions were being sold at a steep discount because they were perceived as "not as cool" but now, these are much rarer than the more common glass breaker models. Same goes for the matte gray blade versions.
