Ive fallen in love... I didnt even know these existed! An emerson, with premium blade steel, crafted by zero tolerance, AND a ti frame lock?! I think ive found my first grail....

However. theres no reviews on it at all that I could find. Could anybody give me ANY insight on this?

Ive spent two bills on balisongs and autos but never a normal folder. So tell me, should I do it? and why?

Oh, and tell me about the knife, too :)
 
There's definitely a slew of video reviews on youtube if that's something you haven't checked out yet. I love my 0620cf, it is mechanically flawless, some people have trouble using the thumb disc to open the knife. It just takes a slight down + out motion with your thumb at the base of the disc, it flies out. I haven't heard anyone mention the very acute tip of this knife, it actually comes to a finer tip than a spyderco military. The pivot is one of my favorite features (even though I don't really benefit from it), it's very refreshing to have a pivot with no torx hole of any kind showing. Also the knife has a dedicated lanyard pin which is another nice touch.

is the carbon fiber nice and "shiny" in the light?

And also, is the second edge, the tanto tip, round, or straight? if that makes sense. its sort looks rounded in the photos

Yeah the tanto tip has belly, not a straight edge.

I have an early serial, so my CF scale might be different than what you'd receive. But I think the newer cf is an improvement. It's hard to say if its shiny, I think so.. When light reflects off of it, the checkered pattern pops.

Thank you so much for your time, and the photos. Everything about this is perfect... except the belly on the second edge :(. argh. ive got a lot of thinkin to do.

Thanks again :)

No prob! Yeah I would like to see how that looks without the belly, it's subtle though. Don't rush yourself deciding :thumbup:
 
I'm going to sell my CQC-7V and get one of these bad boys and grind the Wave off, instead of "ruining" my real Emerson.
 
Ive been in love with this knife since I first layed eyes on it. I havent been able to get one quite yet but I will hopefully soon. That subtle belly is actually one of my favorite things about this knife. It looks like it would be a pretty good slicer because of that. Honestly though, I like almost everything about it. From its nice carbon fiber scale, to its titanium framelock, to its bolt like pivot. Definately in my top five most wanted knives.

If I may ask, why dont you like the wave? It has become my absolute favorite feature on any knife. I dont usually buy knives without waves anymore..

I watched a youtube video of it and the tiny bit of belly on the tanto actually looked really nice on there. Its a much beefier knife than I originally thought.

On a side note, what do you think of the standoffs on it?
 
The belly is very useful, I really enjoy my 0620cf. Worth every cent and came flawless.
 
The ZT0620 and CF version are great knives. The PB washers combined with the heavy blade allow them to glide open like a ball bearing flipper.

The only downside to the knives is that they are on the heavier side, being beefy Ti framelocks with full steel frame and very thick blades.

I prefer a regular Emerson with a covered liner lock and nylatron washers that weighs half as much, but the ZT collaborations are great for people who don't mind a few more ounces and who like the upgraded blade steel and smoother PB washers.
 
I will revive this by saying I liked mine so much I bought a second identical one.

As stated, the only downside is the weight.
 
I want to get a duplicate of mine but I want a 630 as well... tough decision. In any case the 620/630 rocks.
 
I should have held out for the newer 0630.

I will probably sell off or trade my 0620 though.
 
I'm a big fan of the ZT0620CF. M390 is a great steel that holds an edge for a very long time. The CF is really nice looking, but it doesn't have nearly the grip that something like G10 has.

My only gripe is the lockbar relief cutout. I had to adjust the pocket clip to avoid catching the knife on my pocket when I was trying to take it out. It was snagging on my pocket when there was too much tension on the clip right where the relief is cut. When I switched to a smaller titanium clip, the contact point was a little higher, so it did not catch in the same way the factory clip did. I still had to reduce the tension to eliminate the possibility of the knife snagging.
 
I got it from rival. You can look him up on here, usn, or YouTube. All my zt's have rival scales. His stuff is second to none
 
I absolutely love my ZT0620CF. I have not been carrying it as much lately as my 630 has gotten more pocket time but after reading through this mine is going back in my pocket for a while. If you are leaning toward getting one, stop thinking and just do it. You will not regret it!

Just for your information. I dropped mine on a concrete and tile floor and bent the tip. I think any knife would have had the tip bent with this precision drop. I sent it off to ZT and when I got it back the slight belly was gone. It was definitely a straight line. Thought you might like to know!
