I got the ZT302 (Tan scales) a few months ago and have been carrying it as my EDC ever since. It's on the large side. There's a pic of one compared to a Spyderco Military floating around on the forum and there's a significant difference.
The lock up is tight, the Speed Safe system works well when using the flipper, but doesn't always deploy to full lock when using the thumb stud. I'm hoping it'll "break-in" in time, but I think because the blade is so substantial, the thumb stud method might not be most fail safe method. Don't let the, under 4" blade, make you think that you're not gettin' a lot of S30V because what it lacks in length it has in girth LOL!!!
Over all this knife is built like a tank and the fit and finish is just abt perfect. The blade is centered, the scales finished flush to the liner and spine, and the camo on the blade is well done and centered. The camo thing is growing on me. I generally don't like coated blades. My only minor gripe is the clip. With a knife this well thought out, the clip seems like it was an after thought. It works though ;-)
IMO the knife is an excellent combo of the Strider knives designs and Kershaw (Ken Onion).
