I have the 4" with the Zytel Handles and I EDC it quite regularly, I only EDC it for SD as for a utility blade it ain't, it has one purpose and it's well designed for it.
The thumbstuds with a little practice fire the blade out with authority and locks with a very satisfyin' vault like click, it also has a very nice balance which makes it quick in the hands, it supports multiple grip styles equally well.
This knife is a needle and came hair poppin' sharp outta the box, I had some doubts when I traded for it here on the forums, I didn't think it handle well but I was surprised, like all my Cold Steel knives, I'm completely satified with the knife regardless of the negative hype some give CS here, the products are well worth their price point.
I can't speak for CS's Customer Service but I've had their products since the 80s and have never had a problem yet. If I were to lose I'd have to replace it.
Pull the trigger, I think you'll be pleased and if ya don't like it, I'm sure you can get rid of it in the exchnge, (or send me a pm we'll make sure it gets a good home.

).
