Very interesting comments -- thanks.
How is the Star-Tac version different than the regular Zaan?
It just has a really cool different pattern milled into the scales instead of the cross-hatching that the normal one has. It has has a cool lanyard bead and a little Wilson Combat logo on the pocket clip. It's the same exact knives, it's just a special version that CRK makes specially for Wilson Combat for them to sell, and mostly the only difference is the fact that it has the cool Wilson Combat starburst pattern. I also have the equivalent Sebenza, the "Starbenza", which has a similar starburst pattern milled into the scales. They also make the jimping on the Sebenza a little more aggressive. This combined with the milling on the handles make the grip on the Sebenza a lot better and that's to make it a little more "tactical", although I wouldn't consider the Seb a tactical knife. The Umnumzaan is already closer to a tactical knife with the swedge, the more aggressive thumb-ramp and jimping and the better ergonomics and grippy scales, so the Star-tac version is mostly a looks thing. I think they both look awesome but I like the Star-tac that much more. Here's mine:
