Couldn't wait to get this knife. Quality looks great. Unfortunately it is impossible to open with the thumb studs. So stiff it takes both hands to open it. That's the only complaint. Otherwise I would love it.
Fantastic EDC knife!

Like the other review said, the action is pretty dang stiff at first but it doesn't take to long to break in. It fits perfectly in my hand and I even have larger hands. It's almost like it was made for me. locks up nice and tight, has good weight to it and so on. The only minor annoyance I had is in the G-10, compared to everything else I have with G-10 scales this G-10 isn't really that grippy, not bad enough to warrant a lower star review and not quite bad enough to bother with new scales... maybe... I haven't had it to long so we will see. I just wish the G-10 was a bit more rough and grippy.
A Hinderer you can actually carry

I am very impressed with the smaller 0566, much more edc friendly than the 0560/0561 the ergonomics are still just as good- just melts in your hand. The flipper is a bit stiff when you first get it- but it will break in eventually. Also, if you carry in the tip up position the pocket clip can press against the lock bar making it difficult to deploy- adjusting the pocket clip so it's not so tight helps- or carrying in the tip down orientation, then the pocket clip isn't resting on the lock bar. I haven't had much luck converting it to a manual flipper either, just doesn't flip very well without the assist- takes a lot of wrist action. So i just left it assisted and carry tip down- works perfectly.
great every day carry

I love this knife it is a very solid well built knife like all Hinderer ZT models. I have never been into spring assist but this one I love there is no rattle of the torsion bar and just enough tension to give a little extra snap when opening. The elmax blade came very sharp out of the box. This is my new edc I look forward to many years of satisfaction from this tool. Thank you Bladehq and Zero tolerance.
