When it comes to tactical knives, no blade on the market today gets quite the seal of approval as one that Ernest Emerson has had a hand in creating. A lifelong student of martial arts, Emerson has been the designer of knives that are regarded by elite military units, specials forces, law enforcement, and first responders around the globe. The 0640 is an everyday carry collaboration with Ernest Emerson which brings years of experience in tactical know-how into the world of ZT's outstanding manufacturing.
The ZT 0640 is 8.5" in overall length with a 3.75" clipped point blade. Crafted from .156" CPM 20CV stainless tool steel stock, this blade has some of the highest chromium content of vanadium stainless available today. With an HRC of 58, CPM 20CV steel is extremely tough as well, with a very good ability to retain a razor sharp cutting edge. The machine satin finish and stonewashed flats provide an attractive yet scratch hiding finish.
An ambidextrous thumb stud on the back of the blade assists in opening, while the titanium frame lock with hardened steel lockbar insert keeps the blade fixed securely in place while in use, until you are ready to fold it up again. The handle is made from stonewashed titanium, which is not only lightweight but corrosion resistant, in all sorts of weather and climates. The green carbon fiber overlay feels nice in the hand and ensures a comfortable and effective grip. At 4.4oz, you will hardly notice the ZT 0640 is in your pocket until you are ready to use it. The pocket clip is reversible for tip up carry in right or left hand use.
Perfect for tactical use, self-defense, or simply a reliable, no-frills, everyday carry knife, the ZT 0640 will be your best friend in just about any jam. Quick, reliable, and effective; but most importantly it won't get in the way or weigh you down.

The 0640 is a great knife. ZT has several other models that get a lot more attention (0562, 0450, etc.) but this has to be my favorite model and I own several ZTs. I really like the PB washers instead of bearings, reminds me of ZT's version of a Sebenza if there was such a thing. Carry profile is excellent yet you still get a capable/big blade. The YouTubers seems to talk down on the scales, I'll admit they aren't the best looking but the fit and finish is perfect. As for the clip, it looks nice but doesn't work well without modification. I just slapped an extra Benchmade deep carry clip I had laying around...problem solved. This is the closest I'll get to having an Emerson Viper so it's a welcome addition to my collection.
Knifeart is great as usual. Same day shipping on a Saturday, excellent packaging, and best price. ZT and Knifeart do it right.
The 0640 is a robust tool. Just what I was looking for.
I've always admired Ernest Emerson's designs, but this one was new to me. Zero Tolerance has done a great job on this one. and I'm a big fan of carbon fiber. A-1!
