ZT0630: Model 0630ORBLK
Zero Tolerance Knives

ZT and Emerson are back for more with the 0630. The powerful upswept tactical blade, excellent for slicing cuts, is made of Crucible S35VN with a black DLC finish. S35VN is tough and chip resistant and enables ZT to sharpen the blade to a razor edge. When it’s time to re-sharpen, S35VN makes that easier, too.

Of course, the 0630ORBLK features the patented Emerson "wave shaped feature" that enables the knife to be opened as it is removed from the pocket. By the time the knife has been fully withdrawn from the pocket, the blade is deployed and ready for use. A small wave-shaped tab on the top of the blade is built to catch on the pocket seam, opening the knife as it comes out of the pocket. This Emerson instant-open feature is a favorite among military, rescue, and law enforcement knife users.

The ZT0630ORBLK's handle features an orange G10 front scale with a black DLC titanium back. A titanium frame lock with hardened steel lockbar insert ensures lock up security. The reversible pocket clip lets you carry comfortably left- or right-handed.

Frame Lock
Frame Lock
Developed by Chris Reeve, it functions like a liner lock but the lock is comprised of one of the handle scales. It's an extremely strong and easy to manipulate lock.
Pocket Clip
Pocket Clip
Includes a pocket clip for easy accessibility and a more secure carry.
A tougher steel than S30V, it retains the excellent corrosive properties and ability to take an edge, but improves on the ability to hold that edge.

Cons: None
My last glowing review was not posted. Curious. Having had more time to handle, examine, and use it, my impression jumps from a 5 of 5 to an 8 of 5. (I ordered 3 more for gifts-well 2 gifts and 1 in case I lose mine.) This knife is simply an exquisite piece of craftsmanship. The liner lock is spot-on. About 40%. NO movement back and forth or front to back. As solid as a fixed blade, full tang knife. Not bad for a folder! Opening and closing even sounds precise. (I am something of a newbie to knives courtesy of a knife collector friend of mine, but the quality of this knife is obvious.) I can’t buy every knife, but this is certainly enough. Sharpness: Superb and scary. The Emerson Wave feature works so well, the first time I removed it from my pocket it opened naturally without any effort OR thought on my part. I was surprised and a bit scary, but uneventful as the blade opens away from fingers and toward your back. It was incredibly effortless. A great design. The Wave WORKS! (I had sharpened and tuned (replaced a missing washer which he lost) my brother-in-law’s Emerson 8…something with the Wave feature and it seemed “gimmicky.” It is NOT.) So, the stiff detent. It is stiffer than the few knives my newbie hands have handled. Mostly, I open really sharp knives with both hands as it is safer, so the stiffer detent is no issue, but it is NO issue if you use the Emerson Wave feature, I did not notice the detent stiffness. Detent stiffness is no issue for me. Something of a safety issue. I am done looking for a folding locking knife. This ZT knife is simply superb. Me, an Eagle Scout, Philmont Ranger, and father of 3 Eagle Scouts. I know something of backcountry.

Only reason a four is because the detent is so stiff you can barely open the knife everything else is great

Emerson fan and ZT fan so I dig their contributions and their collaboration on this knife to bring us this fine product. I rotate my EDC, this one is in my lineup. The paracord lanyard I made in black/neon orange with a titanium bead when added to this wave opener would make a rabbit spit in a bulldog's face. It is on the large end of the spectrum for EDC; not everyone's cup of tea but right up my alley. Quality materials (thank you), craftsmanship (impressive) and design (thanks Ernie). I like the Orange scale (suppose you could replace it with a custom scale if you so desired or simply didn't care for the bright color; to me the scale(s) is/are not a deal breaker for owning a knife like this) The most significant detail I didn't realize before delivery was; even as nice as Knife Center's website photos/videos are and the many details they list and even after reading reviews, was just how much nicer this folder is in person both to the eye and after handling it. Like a true Emerson, it's a bit stiff until you lube/break it in: it gets better with age.
