This popular, and now discontinued model is on sale for a steal of a price! Get one while they last.

The 0620 folder is a collaboration between Zero Tolerance and Emerson Knives. This knife features the famous Emerson "wave shaped opening feature." The feature is designed so that the blade can be deployed as the knife is withdrawn from the pocket so it's ready for use instantly. The modified tanto blade is DLC coated for added protection and non-reflectivity. Lock up is secure with a solid frame lock with hardened steel inserts.

Better than Emerson
Johnathan B.
Same balance as Emerson but the ZT is better. better blade in everyway, better tolerances, better wave function and so on. ZT is incredible!!! And at the price point wow! Iím not saying that Emerson doesnít make a great knife itís just not as good as this one. If ur in the market for a folder and are not collecting by the ZT over the Emerson. Hands down best choice!
Another Outstanding ZT
Darren R.
I like everything about this blade. It has the outstanding Emerson ergonomics with a better blade steel and overall fit and finish while also costing less at its current price. Mine flips open smoothly and locks up perfectly with no blade play in any direction and no lock stick. And while it is on the larger side for EDC use, I find it still carries well and the wave feature is nice. However and as a word of caution, I would note that the detente is much weaker on the 0620 than any other ZT I have handled (the blade can be shaken open with some effort), and while itís not a problem for me, it is something to keep in mind.
Lovely ZT
Frank C.
Prefacing this by saying I'm a fan of ZT. I own a few of their other knives. This is my first with the Emerson Wave opener however. It's extremely smooth and fast when deploying out of the pocket and took about 5 minutes to perfect the motion.

Elmax steel and razor sharp out of the box. As always, Blade HQ had quick shipping and great packaging so knife was not damaged.
My first ZT
Pete R.
This was my first ZT and man am I loving it! Solid lock up came super sharp perfectly centered absolutely amazing knife.
Great knife
Logan W.
ZT did it again with their great craftsmanship. Love this knife.
First Emerson Opener
Matthew J.
Smooth action whether deployed with the Emerson opener from the pocket or utilizing the thumb disk. Can get it out of the pocket and open with gloves on no problem, closing it with gloves is another story. Kind of wish the titanium lock side had a black coating to really murder out the look.
No lanyard hole but you can tie one around a spacer if you like, it does ride fairly deep. Definitely more tactical than EDC so doesn't get a ton of use but fun.
The best emerson design
Rock solid, you can't go wrong with this fighter of a knife. Not the best at slicing but if you need a knife to pry a door open and still cut this is the knife for you.
Great knife.
Benjamin Z.
I was absolutely blown away by this knife. Itís ecexuted so well and it carries very nicely despite its size and weight. The washers are very smooth and the action is perfect. The American Tanto blade is very useful and the elmax is very tough. If I had to say something bad- itís that I wish it had been done without the thumb disk. Thumb studs wouldíve done just as well.
Great edc
Jon H.
This is one solid knife. The elmax blade takes a super sharp edge and holds it for a long time. This knife has a tight detent and requires a long break in period. It's extremely difficult to open with the thumb disk until it is broken in. That is the only reason I gave it 4 stars instead of 5.
Joe M.
Tough and fast just what I was looking for. The 0620 from zero tolerance and Emerson knives can't beat this beauty its blacked out and has a nice stone wash on the flipside. I will say this Knife came perfect sharp centered and smooth action either deployed from the pocket our from the thumbdisk go grab one while there in stock.
Recent Purchase
James C.
I purchased this knife recently because Blade HQ had it as a special.
I am primarily interested in self defense.
I like a knife with this type of blade and size. I have a few that are similar, but cost a lot more.
The knife arrived quickly and in good shape. The knife had no issues out of the box. Balance is excellent, nice weight, and solid construction. Superior quality at a good price. The "Emerson Wave" works nice. I recommend this knife. I don't use a knife for work, but I can see how it would be a workhorse EDC.
Zero Tolerance 0620 At the Ready!
Russell A.
I received this folder as a gift last year and was very pleased with the weight, comfort in the pocket and it's performance. In fact, I didn't know that Blade HQ rated it as one of 10 Best Emergency/Rescue Knives for First Responders. (I too, work in the security business part time and have carried it in my pocket - "At the Ready!!")
I've used it from cutting rope/string to cardboard box and carried it on several hiking trips. An Excellent working, heavy duty knife that will not disappoint when the chips are down and you need something to cover your back!! The brand name truly matches the blade: Zero Tolerance - Taking Care of Business!!
I love this !
Jesse F.
This knife is absolutely built like a tank. Came sharp right out of the box. I love the g10, absolutely perfect. I love the weight to it and the blade shape is amazing. I would recommend this to anyone that wants a beefy knife
One of The Best Zero Tolerance's Out There!
Jason H.
This folder is outstanding! Absolutely one of the finest production blades I have ever purchased! Fit and finish is second to none! With this particular one you get the Emerson design features with the ZT build quality. I really dig that Elmax steel, the Emerson wave, and the titanium frame lock. 100% completely satisfied with my purchase! Thank you BladeHQ!
Like a katana in my pocket!!
Stephen M.
ZT 0620 Came nice and sharp and the wave shape feature works like a charm. I don't usually like a Tanto knife because they don't cut or sharpen how I like however the ZT 0620 works amazing I had no issues with it in any area. I'd Definitely would recommend this one!!
My new favorite knife
Johnnie D.
I couldn't be happier with this knife. The fit and finish is excellent and in hand you can feel the quality. This knife comes razor sharp out of the box and I love the Emerson wave function. I would recommend this knife.
