My Go-To EDC
James H.
I have a lot of knives, but this is my go-to for every day carry. It is a solid knife that seems to be the perfect size for my hands. I like black blades, but most coated knives scratch off and look bad. The black wash on this is great and won't scratch off like a coating. It is sharp and super smooth to open. A great all around folder.
Favorite knife I own

Absolutely love the design. I de-assisted the knife which is very simple. This is by far my favorite knife I own.
A great knife

Overall this is an excellent knife. Good steel and excellent lockup. The only thing I would say to de-assist it . I waited about a week and should have done it the first day. It took all of 1 minute. And the knife flips amazingly. I think this is the way ZT should have made the knife

As usual I received my knife from Blade HQ in record time!!! As for the knife..... whooooo wheee i like i like!!!! I have been satisfied beyond expectations by ZT once again. I am an official ZT junkie now.
*UPDATE* Got a lemon replaced!

Got my 0566BW today; was super excited to start putting it ti use. Blade looks good, centering is excellent, finishing is good, hair-shaving sharp, swapped the clip to the other side (I'm a lefty), and good to go!

Except the blade rattled. Not side-to-side, either. Top to bottom. Checked all the fasteners, still there. Checked the lockbar/blade mating area, and there's a gap between the lockbar face and the blade, allowing the blade to rattle up and down as the ends of the lockbar face and blade mating face touch each other. The blade's mating face looks all scratched up, too. So I'm the one lucky guy who gets the reject from the production line. Had to happen to someone; no product line is 100% perfect. Guess that's me.

I've already emailed BHQ, and I'm sure they'll replace it, as they're been uniformly excellent with customer and warranty service in the past. Just a bummer that I have to send the knife back out having owned it for less than a day.

Moral of the story is, check those mating surfaces!


Take note, because this is how customer service should be handled.

I emailed BHQ about the knife, described the problem, and they were on it- no questions asked. Ship it back and we'll replace it, or refund you, or change you to a totally different knife if you want. I went for the same knife, and they preemptively offered to inspect it for fit and function before shipping. Emailed shipping updates, constant contact- that's how you handle a problem; BHQ was uniformly excellent throughout. The new knife is absolutely flawless. This should be an example to other online retailers about how to handle issues, returns, and the like.
Best EDC knife
