I wanted to add a couple of notes to this thread.
We haven't discussed them thus far, but since the topic is push knives, I'll mention the 1991 introduction of the Mini Pal.
The Urban Pal was discontinued in 1990, presumably as the Mini Pal was under development to replace it.

I haven't been able to pinpoint when these were offered (I believe it was very early, though, perhaps mid-to-late-80s), but at one point Cold Steel offered these custom-made Kydex sheaths for the Urban Skinner and Magnum Skinner/Terminator.
They feature construction identical to the Ki Quick Draw sheath offered for the Tanto and were certainly produced by the same maker. (I suspect that maker was Tim Wegner, but I have yet to confirm it.) Once again, Cold Steel was way ahead of its time with the application of cutting-edge materials.
