Yes they did.
I don't have the model # etc handy but I'll try to dig up some info.
The knife was released around the time frame of the other Bowies they collaborated on.
It had the regular style Spec-Plus kraton handle and black blade coating.
If memory serves the blade was 10" or so in length. Narrow straight clip-point, fairly thin stock, 3/16" I believe.
I handled one once, pretty fast feeling in the hand!
I always meant to pick one up but never did.
The knife didn't seem to get much attention back then and wasn't around for long.
I'll try to post more info when I can.
