I sent a email to ZT about a pocket clip and screw's never got a email back but five days later a new pocket clip and screw's showed up in my mailbox in my world that's​ outstanding customer service

Just bought my first 0452 today! Your videos are timeless.

I learned a secret to the free spin pivot.... If you tighten it down on the screw side (I mean tight, not like crazy but real good and firm) then flip it over and loosen the pivot side til it's free spinning again and tighten it down again, the knife will have perfect tension as the screw side will spin when the pivot side gets tightened back up once the right tension is reached. It's worked on my 0450 and Reate Hills.

Great video. You sold me on the ZT, now I know how to maintain it. Thanks.

Thanks Nick. Did that with a little bit of grease and now this knife flips like a charm 😉

Great video Nick!!! I just ordered this knife! Thanks for a very informative presentation!

Thanks for this and all your other reviews and maintenance videos. Always informative and entertaining - a great combination.

Thanks Nick. This helped me get my ZT 0452CF centered.

Thank you for this Nick! It may differ with different knives, but this one no bladeplay is perfect centering of the blade on mine. Maybe a tiny tiny bit too tight, but no play and perfect centering.

thanks for the vid man just watching because I just now ordered my second 0452, I ordered the gold EDITION this time so yea just watching vids on the tube!

I bought this knife after your other review. Its such a good knife lol. The action is dummy smooth, its lightweight and sturdy like damn.

the action on this is already ridiculously smooth from the factory...so smooth in fact that I cut my thumb cuticle one out of every 3 times i play with it, when it closes down on it.

Great teaching CLASS Nick, YOU ARE AWESOME!!!! Saludos desde Argentina!!!

I just got one in anodized purple and blue screws from Blades we Love. It's my first ZT and it's absolutely flawless. I have another in mail now.

That oil applicator looks fantastic for keeping in an EDC bag. My bottle of Hoppe's #9 has a needle applicator, too, but it would really easily snap off in a bag or pocket. Wish the things weren't so expensive.

I couldn't resist any longer! I just caved in and ordered this guy! been thinking about it for months, so figure just to get the damn thing lol

Thanks for video Nick!

I just ordered the sprint run with glow in the dark carbon fiber resin, dude can’t wait!!!!

Thanks again Nick your the best !👍

Great review! Subscribed, bell hit! Keep up the great job!

You Sir are the best.

1:29 a year later, you’re now skilled enough to do this nicely. :,)

Great video Nick I really appreciate you doing the 0452 CF glad to see that there is a stainless steel bearing race for the CF side i've been caring mine for about a week and I love it a little large. Also if you ever take apart your 0562 CF please make a video. I know you have been doing a lot of cleaning and disassembling videos I'm not demanding it by any means but I've heard that a lot of people have problems with the pivot even with lock tight thanks again

I like your channel. Subscribed.

I bought this knife recently and it has a rattle in the pivot and I don't know what to do about it but this video gave me the confidence to take it apart thank you

The full blue ti model is heavily milled. Thought it would be heavier but it's not bad and the blue is very nice

I’m thinking about getting one soon

Got mine and after 3 weeks its way off centered toward the carbon fiber side. Thanks for the vid, hoping I can tighten it up and fix it.

Next up, a perspective and review on the art of shaving with a straight razor? I've always been half-tempted to give it a try.

The ZT's are sleepers. They seem to know how good they are themselves because they certainly don't come cheap, but the whole current line of carbon fiber knives is fantastic. I recently bought ZT 0707 and Emerson Kwaiken, both are awesome, but the ZT is the more meticulously finished knife (and cost a few bucks more). The 0707 has a light blade, so the action is not the absolute most satisfying, that's the only negative. The 0452 is something else, I was close to buying it and if I didn't already have the Kwaiken I would have, but but I went with the smaller one, I didn't need another big scary knife, the Emerson has that covered lol.

Awesome tutorial! One question though.. was the blade centering still ZT perfect after your re-assembly?

I just got this knife today. I fucking LOVE it. at 6'3" i do have larger hands. But even my girl with small hands says she is comfortable holding it due to the thing structure of it. It is replacing my benchmade griptilian and i have a feeling i am not going back.

I am missing a center stand-off on this model it seems to have to big gap between the rear one and the front end... why did ZT save on that?

Tip for free spinning pivot: 1. Push with thumb one one side with a piece of inner tire to increase friction 2. When really difficult, get a piece of wood, drill hole, glue in a bit holder. Put one side on bit, use screwdriver on the other side. 3. Buy knives with a keyed pivot :-)

What weight Nano-Oil are you using? Thanks Nick!

you can make the action even smoother by sanding the bearing race up to 12,000 grit the smoother it is the better it is.

I'd definitely be interested in watching a video about your straight razors/safety razors and gear! knife nuts and /r/wicked_edge go hand in hand.

Commenting very early in the vid, you said murdery...lol awesome.

>>>Excellent

I've tore mine down twice now and although it is a free spinning pivot the spring side hasn't spun. I've cleaned it and oiled it and it still don't spin. Hmm

Great video, do one for the spyderco slysz bowie, please :-)

What’s the best angle to sharpen at?

My 0452cf dont have half the action yours does. Maybe it has more lock tension im not sure but iv cleaned it multiple times very well and still the same couple of hard shakes to close action. Nothing like my chaves!

Just love this knife and like my BM 710 SPECIAL it gets shown off a lot but never carried on the streets, they would throw me in the nick( british word for jail) if I ever did.

You have to get all the bolts in before you adjust the action

What's the point to a free-spinning pivot? Does it make the action smoother? Also nick, I found (I'm guessing others have by themselves too) that if you have a knife with a backspacer a la 0808, you can use that to pry open the stop-bar-pivot duo as a first class lever by pinching the ends or just twisting the backspacer.

I want to see the zt 0562cf video

but what about blade centering?

do they offer life time warranty

Hey Nick! I'm not overly smart so I was wondering how you would open up a spinning pivot with torx on only one side? I've tried side loading the pivot but it didn't work out and I thought you might have a better way of doing it.

Nick do you think that a polished detent ball ramp like the Olamic 247 has (just reviewed on the Apostle P channel) would be worthwhile doing ? Or even possible ? My pocket sword also sits by my laptop and I flip it as i watch videos . I may have carried it a handful of times .

Always wanted this one but i hate the free spinning pivot so much :(

This was the perfect knife if it wasn't so dam big!!! The ergos were absolutely perfect and the action was zts best yet. We know a handful of zts have great action but this one somehow managed to be even better. The drawback was the ridiculous size and as for the smaller sized 0450, well ..... it was simply far to uncomfortable in the hand mainly on account of it's small size and poorly designed curved handle shape, ultimately on the 0450 my pinky had nowhere to go and was left hanging.

Thanks for the video!!! 😃🔪

nick you need to do a video on your maintenance kit

Hi I can I use 3 in 1 multipurpose oil or 3 in 1 LOCK DRY LUBE or Dry Lube with Teflon on my ZT knife to lube the bearings? Also, will you put up a video on how to maintain and disassemble a ZT 0562cf knife? Thanks! Love your videos. You are the most knowledgeable, best reviewer of knives that I have come across! I subscribe to and love your channel.

Hi Nick, i can't decide myself if buy this zero tolerance 0452 or the new 0460. What can you tell me about? htx

I love the way this guy speaks.

this knife is easy to take apart. I would say it is much easier than the spydercos.

Nano oil?

how often should i open it and clean or lube it?

I think you should put the knife in a vise when you unscrew the pivot screws. :-) Also, I just acquired a ZT 0456 and it's a little on the stiff side when opening. Any suggestions?

Thank you for the video. I have the same loctite and it is not my favorite.

Your table seriously looks like a wall

It could withstand hard use? since one of its handles is only carbon

Any relation to Barry Kripke?

what does a lockbar insert do?

Can you do a disassembly 0562cf please?

Dude, I hope you bought a modeler's rug for disassembling knives 😅

What's ur thought on the carbon fiber scale with no liners ? has anyone here face any cracking of the scales before upon hard use/regular usage?

I have only two words. "Slysz Bowie!" Say it one more time Nick! Ha Ha Ha..

Frog lube gets nasty after a while. I wouldn't use it. Really fell out of favor with gun people for the most part.

I'm trying to open the free-spinning pivot on the 0450cf and it's impossible; I have it braced on the lock side but the show-side pivot won't budge for the life of me. Any suggestions?

lol funny sound at 15:36

Trade for an 0220?

I’m about 99 percent sure the pivot is a t8

T7? Come on ZT, at least make it an even number. No wonder my T8 cant grip the pivot like it used to after I got some warranty work done.

How the fuck does anyone dislike this? Humanity is disappointing sometimes.

holy shekels

A falling knife has no handle lol

If it needs that much lube then I don’t want it

Hey Nick, Frog lube is terrible. It thickens into a paste and gunks up all of your parts, I hope you stopped using it for the sake of all your knives.

Puts anti rust grease on an s35vn knife. Lol

what cheap made kive

It's a shame for a knife of this price to find the plastic elements to serve as cages for the ball bearings, something that can't hurt to happen on Russian knives comparable to this shit.

I really dislike the 0452CF!! The videos failed to address the poor design of the knife!! Way too light for my liking and rather difficult to open!! Not worth the money!! I picked up an Olamic Wayfarer 247 a couple months ago, which is hands down better then the ZT!! The 247 springs open and begs to be used as opposed to ZT which demands to be closed and asks you to turn out the lights!!!
