The action on this knife is mind blowing. It's just as good if not better than the majority of my Reate knives. Kizer knocked it out of the park with this one.

I was on the fence about returning this knife for about a week as I kept learning about it and knives in general.
I think it's a great knife but there are some caveats that are mostly related to being left handed.
Most frame lock knives are meant for right hand deployment and carry. With this knife in your left hand, you'd better be sure that you are not applying any pressure on the lock panel with your thumb as you try to use the flipper, because it will seize. You might stare at the knife and wonder as I did what the problem with the pivot is, until I figured out the pressure thing. This also affects the ability to reverse flick with the middle finger. This knife has a heavy detent and I just can't do it. I can't do it with my thumb either actually, though I can do a slow roll to half-flick using both my thumb and forefinger on both sides at the same time to clear the detent.
Aside from these issues, I really like the knife. I like the feel of the titanium sandblasted finish. The ergos are good. The factory sharpened blade edge is fine. The dual sided pocket clip is appreciated (though a bit ironic!). It's a good size and feels good in the pocket.

Smooth, centered, and well thought out, the stealth filler tab is awesome too. The oxide blast looking finish feels good, just know that it will get snail trails.
