Zero Tolerance ZT0006 Knife Disassembly

Zero Tolerance ZT0006 Knife Disassembly
Known worldwide as the Tiger, the Panzerkampfwagen VI was used by the Wehrmacht from the late summer of 1942. It is considered one of the most famous tanks in history, despite its modest production number of only 1350 units and the resulting low strategic importance. The development of the heavy tank can be traced back to 1937, and series production began in August 1942. Today, there are only seven preserved units, which are exhibited all over the world. Due to the low availability, the so-called Frankentiger was even assembled for this purpose from wreckage parts of different production years.
The tank parts we use come from a Tiger I of the Schwere Panzerabteilung 502, which was destroyed in combat in Latvia in the summer of 1944 in a heavily wooded area near the town of Bauska. Based on the wreckage found at the original excavation site, it was determined that this Tiger was an early to mid-production model. Examination of battle damage to the remains, military records and local historical accounts revealed that this Tiger tank collided with both a Russian T-34 medium tank and an SU-76 anti-tank gun, and was also damaged by a stationary 45-mm anti-tank gun. It is still unclear which of the impacts caused the most damage and sealed the fate of the Tiger. However, as several 76-mm fragments were lodged in the heavy armour, it is assumed that a nearby T-34 landed the decisive hits before it was destroyed 300 metres away, too.
Otto Carius and Albert Kerscher, two of the most successful tank commanders of the Second World War, were attempting to stop the advance of Soviet forces on Riga at the time, with the Schwere Panzerabteilung 502. The division was able to so devastatingly defeat the enemy blockade forces near Tukums that it was able to retreat to the Latvian Courland together with more than 500,000 other soldiers of the Heeresgruppe Nord. There the forces were encircled in the further course of the Soviet advance. The Kurland Cauldron served as a bridgehead and could be supplied by the Kriegsmarine via sea. It withstood six major attacks by Soviet forces until the unconditional surrender on 8 May, 1945.

Looks like I would expect not sure how in the world of physics this tang is a con or a weak spot. Good for them for taking the extra step to cut weight. Zero negative aspect here what so ever pure pro and dedication to a nice knife.

[@Totemparadox]

People don't know, but many of their favorite close to indestructible full tang knives are heavily skeletonized under the handles. If the edges and corners are properly rounded then it's not a weakpoint in the slightest.

[@avatarion]

It's not going to break inside the handle, especially with 3V steel. Smart weight reduction design.

[@mikeyeh7646]

Thanks for the disassembly. Hopefully from the skeletonisation the whole knife is balanced. Oooo, I can’t wait for the boys from Dutch Bushcraft Knives to do their testing on this knife. 😁😁

[@Iamthedudeman00]

The skeletonisation isn’t necessarily a weak point, look at how much material there is still on the handle side, also a lot of people don’t think about that the G10 is very strong and it can add strength to the handle, because for the handle to actually break, the g10 has to break as well. The G10 will also absorb shock as well. You have absolutely nothing to worry about. If you ever have seen the destruction video of the Glock field knife videos, that thing doesn’t even have a tang, and the reason it is so strong is because it has a tube shaped polymer handle that is made of Glock proprietary polymer that is known to be nearly indestructible. The tang of the knife isn’t the only thing that keeps a knife strong, now for this knife you have a 3v handle that is sandwiched with 2 slabs of G10, the handle is the last thing you should worry about.

[@DirkWerning]

100% agree with you. And great point the G10 adds to the strength for sure!!!

[@dein45d]

Thanks so much for the disassembly, as I was curious as well. Love the design, and that it is balanced. The angles of the skeleton cuts are correct. If y’all think this is a weak spot, study bridge construction. Just ordered from Gil, maybe this exact piece!

[@matthewgibson264]

Looks strong enough to me, considering the steel used also. Probably super strong, plus the g10 adds strength

[@user9b2]

Given how thick the stock is, the handle should be fine - so long as you use proper lock tight.

[@watchsixto]

That's a good point on if it does save on the weight due to being skeleton handle

What a great looking knife. If i already didnt like my fallkniven a1xb so much, I'd pull the trigger

[@blackhawkbushcraft]

Thanks for the video! 👍 Full-tang, skeletonized blades are very common with many manufacturers. Skeletonizing is a way to reduce material to achieve knife balance without compromising the structural integrity. That knife will serve you well and last a lifetime. 👍

[@DirkWerning]

Agree. Thanks for watching.

[@CadillacDriver]

That blade would snap before the tang. Assuming the load is placed half way along either.

[@stangbladeworks3579]

I wouldn’t worry about it at all. Especially considering it’s 3V. I have tried to snap hardened blade steel and it’s almost impossible at that thickness. I couldn’t imagine any reasonable task being able to break that tang. I think if you were on a mission to destroy it you would need to mount it in a vise and use something to gain a ton of leverage, maybe a long pipe.

[@DirkWerning]

Totally agree with you there. Hmm that might be a fun video to do…but Cold Steel has already done a bunch of those type of videos 😂😂😂 Well that and it’s just a loaner. Lol

[@gamer.004]

I mean nothing is truly destruction proof, especially if you watch DBK. I like thinking of knives as vehicles. They where made for a purpose. And outside of that purpose they can fail you, but inside, they will thrive. Folders are sport cars, no off-roading mate. Fixed blades are trucks and tanks, they can go off road and pack a punch, but they can still blow up if you nuke em. This knife is a tank from what I understand, and I have high trust for ZT. So don't go nuking ((vice and pressure snapping)) your ZT, it's a Zero Tolerance for Peet sake. 😭

IT never ceases to amaze me regarding Cyber commando giving there 10 cents worth backed up by nearly no experience . The NUT in that handle idea was coped from a knife made over 20 years ago called the Chunky Monkey made by Wilkins knives and Jordan Knife design collaboration . The buttcap slot is coped from the Raptor Buttcap made some 15 years ago made by Jordan knife design and Templar - knives . As to the comment regarding the void space in the Handle makes it weak . The thickness of the tang and the distance from the edge to the slot is wider than the Thickness . This was done entirely to get the near centre balance . I would like to see the TEST where the handle Tang snaps because of this Cyber commando idea its weak . That construction will take a lot of use . The two holes in the tang are for wrapping para cord around the handle in some situations . The stainless blade makes it a good choice for wet conditions . One big problem is the rattling Kydex sheath it comes with , that needs addressing for combat carry .

[@DirkWerning]

All great points. Thanks for chiming in.

[@W49Boowie]

One piece of information that you got entirely wrong is when you stated that the blade of this knife is " Stainless " when 3V barely qualifies as a " Semi-stainless " steel. The formula for CPM3V contains 7.5% Chromium and what boosts it's minimal corrosion resistance is that when heat treated correctly the Vanadium in the formula forms into Vanadium carbides which provide the bulk of 3V's edge retention and fortunately because Vanadium carbides form at a lower temperature than Chromium carbides do it means that there's more free Chromium left in solution in the steel matrix which means that a passive layer of corrosion resistance is provided. For a steel to be classified as " Stainless " it needs to have a minimum of 12% Chromium in its formula. Other than that small mistake your breakdown of the knifes construction and your details about this knife models comparable predecessors was incredibly interesting indeed, well done, 👌🏻🤝🏻.

[@Jugend88139]

It reminds me of a LIONSTEEL 5 skeletonized full tang that JOEX manage to litterally explode...

[@daleoutofdoors3606]

So what if the little screw and nut securing the pommel is compromised and the knife is discontinued? Is that some kind of standard part? Seems like much integrity relies on that one screw and nut.

[@solomonkane408]

I didn't think it had cutouts it could affect heavy heavy use but I don't think it will in general I think the whole knife comes apart like that to make replacement handles and the holes are for lashing like a spear since it's and outdoors knife . Great inside look .

[@DirkWerning]

That’s a good point. Pull the scales and lash it to a stick and BOOM.

[@johnruff7417]

Knives with guards will break at the guard because the blade stock gets narrower under it causing a stress riser. It’s 3V so I’m sure is as tough as you can make a knife of that style.

[@user9b2]

Not with this knife, take a closer look.

[@LaughingCrowcorp]

I too wish it was more solid, i dont care how much extra weight it adds if it also adds durability

[@DirkWerning]

I think it’s totally fine as is 🤷🏼‍♂️

[@rhettlyerly545]

Unnecessary weight and unbalanced design are not really positive features. Even the Becker BK knives have lightening cuts under the scales and they are often viewed as sharpened pry bars.

[@clem8fan]

Thanks for the disassembly! I'm not sure how much of a weak point it would be since your going to have to really point load that handle to cause it to fracture there with the scales and everything but still full tang without the weight relieving would be better for overall solidity I guess. 3V is pretty tough stuff so I think it should be fine for most use, at least any outdoor/camping activities I'd put it through. Definitely would like to pick this up!

[@DirkWerning]

Agreed.

[@brandyhouston2105]

Always have a backup 😎💯

[@schlooonginator1227]

Those lightening holes don't look to weaken it too much so long as it maintains the full thickness exterior. I would argue a Fallkniven A2 has a weaker design and no one is calling those knives weak. It's more important to avoid sharp transitions creating stress risers. Jimping can greatly weaken a knife and it's a common feature on survival knives. Watch the DBK BRK Magnacut failure. As long as the outline avoids sharp transitions it should be fine but that guard can also act as a stress riser if the blade flexes but it's bound at the guard. As for the Jimping on this knife it looks smart having rounded grinds minimizing negative affects.

[@ArchimantisTF]

I hate skeletonized handles when they are done wrong, most of the time with stress risers, big holes and less steel, or a hole too close to the guard. This one seems perfect, everything is rounded, thick and placed in the middle with plenty of steel left. It looks like a beam for a bridge or a building. And the pommel is cleverly designed: it does not maintain the scales and the guard, and the screw will absorb shock and preserve the full tang handle.

[@DirkWerning]

Yep totally agree. Thanks for the input.

[@scottindefatigablish6291]

Excellent comment. I am looking at that thing trying to work out how exactly you would damage the steel in the handle and unless you have hands like the hulk and can crush buildings with your fists I don't really see it. In reality very little theoretical strength was lost here and in the real world that will be zero for all practical applications. The real cost is a bit of extra machining time which is probably five or ten bucks to the consumer and most rational people would take that for better balance and weight. I also agree about the pommel. It is something most knives of this type get wrong and this is simply a good way to do it for strength and longevity. We are talking about design here, this is an example of great design. Zero tolerance is getting its act together it seems.

[@willienelsongonzalez4609]

I wonder if those additional holes are there if you want to use the knife as a spear? Those smaller gaps could be used as storage for tinder tabs, small ferro rod, water purification tablet? Definitely would love to get the knife and try it out.

[@fettmaneiii4439]

this big choil in front of the guard is a bigger concern than the handle skeleton for me. the further the cutting edge starts away from your hand the suckier it is to cut with. doesnt really matter for a pure combat knife though.

[@beaker2000]

I don't think the cutouts are a weak point at all, the remaining steel is plenty thick enough to as not to impact the overall strength of the tang for any purposes a knive would be used for. The nut on the pommel is the only concerning thing to me as it is for striking by it's design. While the load is transferred into the tang for striking, it is a small thread and nut holding it. Having said that, this is a very well made knife, I would be happy to have one.

[@DirkWerning]

Agreed

[@philwilliams3657]

There is nothing wrong with this construction 🤦‍♂️

[@Roger-wr1cm]

It's quite normal. When you look at the trc apocalypse, it's got similar maybe even more aggresive weight cut out beneath the handle.

[@DirkWerning]

That TRC is AWESOME!!! Buddy loaned one in. Was a tough one to send back lol.

[@ArlenShawcross]

I cannot imagine a scenario where one would put enough stress on that handle for those holes to be an issue. Properly heat treated blade steel is insanely tough, and we know ZT has a good heat treat recipe. Well done video and thank you for the look under the scales, but I think this is a non-issue.

[@carl8229]

[@BushCampingTools]

I see people are worried about how strong this knife is. Just think about it, one can hang off a cliff with nothing but a few pissy bits of aluminium (not even steel) supporting them. If the tang was totally solid this would be some super heavy knife and too weighty in the hand

[@steveburdette1478]

You would have to drive it into something hard all the way to the hilt then try and bend it to break the handle. Or smack the handle with something hard. I feel like your still more likely to break the blade

I desagree... Cutting the truss like holes in the tang is essential... It would have been way heavier... I don't think you can really break it, Steel is strong.. Also those other 2 holes were probably for bolts durning the milling process..
