I found this exact model knife sticking out of a gravel bar of the Illinois River in February, 2022. This five year old video will help me bring it back to life. I appreciate you making this disassembly/reassembly video.
The multi-washer configuration is likely not a cost-saving measure. At least, multi-washer configurations in general are not automatically/objectively a cost-saving choice (though choice of materials, etc. may still involve cost-cutting). The more likely reason for using two washers is to ensure that the bearing (slip) interface occurs between the two washers, thus providing very consistent performance with regards to friction and wear characteristics. If you only use one plain bearing, then the slip interface must occur at either the blade/washer or frame/washer interface, and friction here cannot be controlled nearly as well. Typically, neither the blade nor the frame is properly prepared as a friction surface (with regards to surface finish, or the material itself), whereas the washers are expressly designed as bearing surfaces, so using two plain bearings together is a great way to produce a fantastic low-cost rotating joint with consistent and predictable characteristics. Actually, next time you clean this knife, or any knife with two washers on each side of the blade, you might try specifically NOT lubricating the washer/blade and washer/frame interfaces, then applying MINIMAL lubrication between each pair of washers. This way, only the washer-washer interfaces will slip.
Little trick that I use for speed safe knives to keep the door on when reassembling it is to just put a tiny piece of scotch tape over the edge of it and and inside of the handle. You can't notice it once the knife is together but it certainly helps keeping the pieces together as you do.
I have carried the Cryo 2 for well over 3 years with no issues of grease leaking at all. I just did my first full disassembly and cleaning. Grease is holding up great. Used a little Ballistol to clean the gunk in between the two sides.
My brother! Like always, what an amazing work you always do! I bought that exact model a few years back... But Im thinking I will just leave it without cleaning for a little bit longer..lol! Thanks so much Nick!
I just finished cleaning my kershaw assisted cryo and I am glad I found your video. I took it apart then thought about throwing it away after seeing all the little parts. Glad I continued to watch your video. I cleaned it and while reassembling I discovered that when trying to mate the two parts it's easier with the blade side laying on a flat surface oil where the thin brass washer goes then put it where you can see where it has worn it outline. Then, put the door on and the holes at the top will automatically line it up for you, then put you torque wire in the little hole and then put a dollop of grease on then the other washer and finally put the other side on.
Hi Nick, me again. I found this at Kershaw Most Kershaw knives require a Torx bit #6 or Torx bit #8 to fit into the head of the screws. The Torx #6 fits the pocket clip screws, handle screws, and safety lock screws on all current model Kershaw knives. The Torx #8 fits into the pivot screw. Some older models (prior to 2000) may use a smaller torx bit #4.
Nick, You really saved my Ass with this video. I sharpen knives for friends and family... When finished with the sharpening and inspecting my work, it became evident that a lot of schmoo, pocket lint, grit etc was inside the knife. Lets clean up the knife and return it good as new, OCD has a down side... To my great horror the speedsafe assist dropped on to my table as the knife was being disassembled. Yikes, Crap, Really? For God's sake no, no, no.. I might be going to Walmart to buy a Kirshaw... It was a pain getting this knife back together... With the video it was possible.. THANK YOU, THANK YOU, THANK YOU VERY MUCH... : )
I picked one up today and so far I really like it. I love how you can move the clip so I can carry it in my pocket with a lynard attached for fast draw. Thanks for sharing God bless.
I'm pretty sure you put that washer on the wrong side of the door. Also reassembly is much easier if you just put the door and spring on before the scale.
Josh Starkey the washer is correct on the side of the door. If you watch back to the beginning, he flips the door over when he takes it out, and so the washer that is then facing up, was on the inside
I like what you do, but im in envy of your tools. Im sure if ya branded them, people like me would buy! Youd be making millions, negating many guarantees, but it'd be worth it! You do fine work, man!
thank you! I disassembled a cryo 2 and this was still helpful. It had been years since I messed with a speedsafe pro tip when you disassemble a knife do it over a tray or paper plate or something because washers or screws or little pins like to vanish. Also take a picture or a moment to study the knife as it comes apart. they come apart much easier than they go together. The Kershaw cryo series are one I always recommend to people who are just getting into knives and are ready to move up from a gas station junk knife. The Cryo is a beast, has a very satisfying action and is also very easy to sharpen
I think this must be correct, as the milled out pocket for the speedsafe door doesn't have an additional pocket area for the washer. You would think the handle/scale would have an additional pocket to fit the washer if it were designed to have the washer between the scale and the inside of the door.
That's really interesting mine only had one washer per side and they are significantly thicker then your ones. I opened mine and relubed it because it was really scratchy. What's really weird is that the knife now wont properly actuate. The blade gets stuck. But it's not because I overtightened the pivot. It does it even when I completely back the pivot screw off
I used your instructions to disassemble a Kershaw 1555TI and the 2 washers that come with it are for each side of the knife pivot point. I got it all assembked & the only problem I've noticed is the lock bar doesn't go into place to lock the blade in the opened position. When I pushed it in it stuck?!? What would cause that? The knife deploys better than it did before. My hubby found it & I took it appart & it had a lot of black gunk mixed in with the grease & there was dome rust that I buffed out & I put a thin coat of silicone grease on it & wiped it off leaving such a ghin costing that you couldnsee the grease. I used silicone grease on place of the red grease you used. What would cause the lock bar not to work?? I'm at my witts end trying to figure what the problem is eith the lock bar not functioning.
Maybe it would be easier to reassemble if you started with the speedsafe side down? And build on top of that? That way you don't have to worry about the door or anything, and the only thing your trying to manipulate is the blade itself
My version came with one copper washer that was standard thickness. If anyone is curios about removing the thumb stud it does not screw together. It is pressed together like a rivet, so you will have to grind it off with a Dremel.
Would have been a lot easier if you didn't try to assemble the whole speed safe mechanism into the scale and fidgeting with it onto the knife. Should have installed the washers and blade onto the bottom scale. Then install the speed safe plate, torsion bar(hook the one end into the blade hole then just leave it laying in the middle of the plate and it will go into the speedsafe chamber/cutout) then the top scale. Would have been a lot easier and less messy.
as long as the bits fit well, no problem. But on a new 1830 (OSO), the Torx #6 will not quite fill the small screws. The Torx #8 bit works well on the pivot screw.... But the Kershaw kit of bits has only #6 and#8 sizes....
Thank you for your instructions. Nano lube can be replaced with motor oil. I have put some nissan motor oil (5w-30-dpf)and it goes ultra smooth. How have you detatched theese cylindrical thingies from a blade?
My Cryo II's pivot screw came not entirely flushed into the body. Saw in your video that you didn't bother removing the pivot screw on the opposite side (in the video, you said an ancient evil was holding it in place). Should I attempt push it out?? Or just leave it in peace.
I do not have the correct drivers to take mine apart but the spring no longer works on mine. I am not sure if it broke or slipped but it no longer works. The knife stays closed when it is closed and stays open when it is open so with the lower cost of this knife and the fact it is still functional as a knife it does not bother me much. At least not enough to buy the bits just for this knife.
As far as the thunb studs go they really dont get in the way maybe for some people when removeing the thumb studs heat them up frist? So it makes it easy to remove them unnecessary in my book?
Bought one of these on sale at bass pro two weeks ago. The assist stopped working earlier today. Took it apart and the spring had snapped. I've deployed it less than a hundred times. Put it back together "deassisted" and it's a slug. Putting it back together was a nightmare. I'm done with assisted knives, and I might be done with Kershaw.
I've got the D2 steel version of the cryo and it only has a single copper washer on either side of the blade. I wonder If the difference was just a revision in all of the designs or if the harder tool steel of the D2 version doesn't need a second washer.
I carried this knife for almost a decade without all this "maintenance". The only time i disassembled it was to replace the torsion bar. This guy is nuts.
I took mine apart and realized I didn't have any extra grease after already wiping off the stock stuff. So then after spending literally half an hour jamming the washer into place and trying to keep it there without everything falling apart, it resulted in a knife worse off then it was originally due to rattling in the assist chamber... Obviously I'm not blaming you, but I now know to stay away from taking apart assisted knives...
My Cryo came with Teflon washers, is it normal for a knife brand to use different materials (ie. Metal washers vs Teflon washers) in same models? My version is the 1555ti. Thoughts or comments? Thx!
My friend’s Kershaw knife is suffering from terrible early lockup that makes it unsafe, I’d like to fix it for her but I also think I’d be out of my depth taking it apart with the speedsafe. Any suggestions?
It is much easier to assemble the knife putting the spring onto the blade then the cover. You have chosen a very difficult route to re-assemble the knife.
Hey Nick I have a benchmade 940-2 first production 61 out of 1000 just wondering if I should use it or she could be worth some value down the road I know it's not a very high-end
Bought a kershaw cryo for my PA camping trip and it failed first day! The speed Safe broke while flicking it out by a fire. After that it was useless....not a happy camper.
I hate the original pocket clip placement and the thumb studs definitely get caught bad in that config. Heading to the store to grab a driver to fit it and hopefully rectify
I have one of these that i got a few years back (or like a newer version of the same model?) I was thinking about cleaning it but had no clue how to put it back together. Now i can take it apart with no worries.... Well... You know, other than the fact this knife looks like a bitch to assessable compared to my other ones.

I just took mine apart, and when putting it together I just attached the back spacers to the speed safe side of the body and they hold the door on.
Thank you. After watching this video I now probably have a sporting chance of putting my kershaw filter back together again...
Hope you succeeded
I have carried the Cryo 2 for well over 3 years with no issues of grease leaking at all. I just did my first full disassembly and cleaning. Grease is holding up great. Used a little Ballistol to clean the gunk in between the two sides.
By takeing the plate out put some roller washers in you just made yourself a perfect slipjoint works for me
Pro tip: don't disassemble Kershaw cryo
Thanks for the video, without I wouldn’t have been able to reassemble my Cryo. This video was a great help, now it works flawless again. 👍🏻😊
My brother! Like always, what an amazing work you always do! I bought that exact model a few years back... But Im thinking I will just leave it without cleaning for a little bit longer..lol! Thanks so much Nick!
yea, like ever, lol

Just fixed mine. I thought it would be difficult reassembling, but it was actually pretty simple. Thanks for the video.
"Looks like Kershaw hates us" lol your the man Nick!

It was a pain getting this knife back together... With the video it was possible..
THANK YOU, THANK YOU, THANK YOU VERY MUCH... : )
Thanks man, really helped me with my cryo 2 tanto. The filth that i found explained the grittiness that i felt when deploying it.
Nick, you're the Bob Ross of knife maintenance :-) Very relaxing and entertaining to watch. KnifeZen achieved ;-)
We're just going to put a happy little dollop of grease over here...
i agree
Nick is a lot of great things. Relaxing is not one of them.
I picked one up today and so far I really like it. I love how you can move the clip so I can carry it in my pocket with a lynard attached for fast draw. Thanks for sharing God bless.

This guy should do cartoon voice over work.
He sounds like Billy Crystal's character Mike Wazowski from Disney's Monster's Inc.
Timone from the lion king
Fist knife I've ever seen apart. Thx for being my first Nick. LOL
I like what you do, but im in envy of your tools. Im sure if ya branded them, people like me would buy! Youd be making millions, negating many guarantees, but it'd be worth it! You do fine work, man!
One of your earlier ones. You have come a long way!
I lost my Cryo before I got to service it. My Cryo 2 however had only 1 washer each side and no washer was behind the speed safe door.
thank you! I disassembled a cryo 2 and this was still helpful. It had been years since I messed with a speedsafe
pro tip when you disassemble a knife do it over a tray or paper plate or something because washers or screws or little pins like to vanish. Also take a picture or a moment to study the knife as it comes apart. they come apart much easier than they go together.

The washer goes between blade and the speed speed door . Not between handle and speed speed door .

I think this must be correct, as the milled out pocket for the speedsafe door doesn't have an additional pocket area for the washer. You would think the handle/scale would have an additional pocket to fit the washer if it were designed to have the washer between the scale and the inside of the door.
Good video. Thank you for posting. Would you recommend replacing the washers with something else?
@@TheAtarashiiKaze No I would not change whit barings because is spring assisted. All and all it's a good knife for a flipper.
Nick unnecessarily made this simple task as complicated as possible.
I own a couple sets of the kershaw cyros in my collection.
Well done
Yes you can desist with bareings also just as well o just dont forget to drill a little notch by the detent ball and than your set?
That's really interesting mine only had one washer per side and they are significantly thicker then your ones.

Now I know how to clean my Cryo, Kershaw uses locktite on the clip screws when I moved mine they semi stripped
Now I have to get others.
Love it!
Thats some , High quality H2o. 😉 It's me yah daddy Roberto!

Send it back to Kershaw and they will return a brand new one all checked out! Don't be stupid...

This is an excellent EDC; though bit heavy/over engineered.
Is the Cryo 2 the same in terms of taking it apart?
How did you remove the thumb studs?
This is why I don't take things apart. Trying to get things back to the way they were seems to not work well for me.
Seen some people around using loctite... Does it make any difference? Would you recommend it?
Mine was a pain to service, and if you don't get the oiling just right it won't work properly!
What size torx bit is the pocket clip?
I took mine apart and realized I didn't have any extra grease after already wiping off the stock stuff.

There wasn't any loctite in your because they must have put all of it in mine. I can't get it apart.
It is much easier to assemble the knife putting the spring onto the blade then the cover. You have chosen a very difficult route to re-assemble the knife.
If someone woke you up at 3 am, would you sound like that?
Hey Nick I have a benchmade 940-2 first production 61 out of 1000 just wondering if I should use it or she could be worth some value down the road I know it's not a very high-end
what is the cyro's male pivot screw size? I have misplaced mine and i'm looking for a replacement screw
Can anyone els with one tell me how lose the lockbar is, mine feels extremely loose
"Aww damn it" 😂
Nice video but blaming Kershaw because you assembled it wrong is not Kershaws fault.
what is that oil you use?
Not much material around the axle in blade... Is not strong
When did peter griffin start messin with knives?
Hey nick, old video but can i ask if it's possible to de assist the cryo? Thanks!
You can but its' a bit sloppy. There's a video showing it here on youtube, but not from Nick.
The moment you discovered mixing grease and oil. 11:54.
Thanks for the video just put my Kershaw cryo-back together and have an easier time than you did thanks again
Bought a kershaw cryo for my PA camping trip and it failed first day! The speed Safe broke while flicking it out by a fire. After that it was useless....not a happy camper.
Kershaw ember (3560)

That knife it's not for me. I like simpler things.
I have one of these that i got a few years back (or like a newer version of the same model?) I was thinking about cleaning it but had no clue how to put it back together. Now i can take it apart with no worries.... Well... You know, other than the fact this knife looks like a bitch to assessable compared to my other ones.
wish I had your cryo, they loctited the crap out of mine
Took the paint off my gray blade and stone washed it now my blade is all. Scratched up don't mater anyways maybe it will stay sharp er
r u felling ok man
I love you
Alahu lahkbar. Itsa beautiful thing.
Just grabbing a random bit.......ehh close enough
Ive decided not to open my knife after this😂
u should have left the speed safe out!!!!!
Sadly, it also doubles as the detent. Not my favorite thing about this knife for sure.
Wow! After seeing how much of a mechanical monstrosity this knife is, you just inspired me NOT to get one! Thanks nick!
LOCK BAR 😂
Dislike is tangible....
Blaming Kershaw because you can’t put the speed assist back together correctly 🤦♂️
Nick! whays wrong with your voice? Are you feeling sick? :c
Hah, tired as heck when this was filmed. A few days before a big international trip, too!
+Nick Shabazz Don't leave us.
ill litteraly cry.
I've been back from the trip for 20 days now! Don't worry, I'm stealthy like that.
Asd
LOL😂😂
Who is this guy? Is that a fakd accent. I need to know, just like tom petty did
LOL
You screw up and then blame Kershaw. LOFL!
