The Escort has been out for a while now. I got one of the very early ones and I found the detent to be a little weak but acceptable. It's kind of "Hinderish" where you can learn a technique that doesn't really require a wrist flick, but you have to kind of direct inertia. My detent is certainly strong enough to keep the blade in the handle. I do wish the detent was a little stronger, as that would make it a better flipper, but it's certainly functional as is. People pay a lot more money for knives with a worse detent.
My issue with the Escort was it fell apart after just a little use. All the screws seemed to loosen up, including the pivot, allowing the blade to go off center. I disassembled the entire knife and reassembled with a little loctite and it's been fine ever since.
I think Kizer might be overly ambitious to roll out a bunch of new knives. My Escort is the second recent Kizer I've bought that didn't seem to have been tightened up on the assembly line.
