Kershaw Composite Blades

Blah blah blah, please don't feed the troll, people always will complain about something they don't understand.
It's damn tough, good luck breaking it. Appearance is a factor, but so is flexibility and reduced cost. If any other company can produce a $70 Zpd edged knife, besides Kershaw, please enlighten me. Their CB blades offer high quality steel at good prices, so why complain?
Don't buy them if you don't like them, just because they don't appeal to you doesn't make them a waste, this is America, newsflash, nobody forces you to buy them.
 
Thomas, I'm not trying to get you upset or cause a problem. I use my folder generally for relatively light EDC tasks which obviously won't test the blade to the point of failure. However, alot of us here do openly or secretly like to judge a knife by seeing it taken to the extreme, to the point of failure. Lynn Thompson and noss, for example, are popular in part because they openly test different knives' breaking points and we as consumers get more information to judge our knives by, even though most of us will never take them to this level of abuse.
 
I think it would be good to point out here that these things are indeed tough. When the Tyrade first came out they had a sample blade which had the edge snapped off in a vice (or similar) to show what happens when it breaks. When torn out there is very little separation at the weld, the two pieces of steel are stuck together pretty well.
This is not entirely due to the welding though, Thomas pointed out that it's more a matter of just having two pieces of steel tightly fitted together. Even without the weld you would have a hard time breaking the edge off (think of very thick jigsaw puzzle pieces).

Blah blah blah

Worshipping at the alter is no reason to ignore material properties and limitations of a design.

Apparently you're privy to how these blades perform under bending, impact, and time. Please show use the results of these tests, including some proof of increased flexibility - a picture showing a composite blade bent to 60 degrees or so in comparison to a conventional blade will do.

If there is no proof of being a "higher quality" blade other than being made with good materials and using an advanced method of construction, how does one determine this "higher quality". Where is the advantage, the "better than"

I note that experience indicates Kershaw has no lack of craftsmanship in making their knives.

As for $70 ZDP, that is pricing issue. Spyderco has offered some that can be had for such. However, who cares how much a knife costs if it falls apart when you go to sharpen a stick or such (lateral loading, you know)?
 
I'm absolutely a fan of the composite blades, and I think it's a great idea for normal EDC. (And they're beautiful collector items, e.g. the G10 Tyrades. :thumbup:)

Keep'em producing! :thumbup: (Please, make some Sandvik/D2 CB Cyclones too! :D)

But that's a fact, if I had to pry or stab something, I take out my small fixed HD knife. :cool:

Now you're bordering on trolling.

Thomas, along with multiple users of Kershaw's CB technology have said there is no issue with the strength of the weld.

As for "ignore(ing) material properties and limitations of a design" you're talking out of your hat. Did you read the part about matching the proper steels (spine and edge) because of HT issues?

The "I note that experience indicates Kershaw has no lack of craftsmanship in making their knives." shows just how little you know about the company. Do your homework before you come in here spewing drivel and being argumentative.

And yes, a full blade of ZDP will cost more than a CB with a ZDP edge. It ain't advanced economics.

As for the falling apart while sharpening a stick comment, it deserves no reply. Trolling pure and simple. You know?

Just what do you consider higher quality then?

I sure did and I don't know how they were using them or how this was determined. Technology often succeeds short-term, but some issue comes to light from some stress or material issue not thought of. The real world is often harsher than testing.

As for "ignore(ing) material properties and limitations of a design" you're talking out of your hat. Did you read the part about matching the proper steels (spine and edge) because of HT issues?

Okay, matches were made for heat treat and allowing for bonding - what is the final product's performace?

The "I note that experience indicates Kershaw has no lack of craftsmanship in making their knives." shows just how little you know about the company. Do your homework before you come in here spewing drivel and being argumentative.

So I take it you believe Kershaw does have craftsmanship issues. They seem reasonably well made to me. Perhaps you've had bad luck.

And yes, a full blade of ZDP will cost more than a CB with a ZDP edge. It ain't advanced economics.

On what data do you base this on? Extra machining and the bonding steps add cost, I don't know what these costs are. Do you?

As for the falling apart while sharpening a stick comment, it deserves no reply. Trolling pure and simple. You know?


Sharpening a stick, to make a peg or such, is a common outdoor practice that puts a transvers load on a blade when you bite into the stick. If the bond is weak, this could result in delamination.

I put quotation marks around the phrase "higher quality" since such a determination is made based upon a comparison to some other thing.

In the instant case, are these blades tougher, do the blades sharpen more readily, hold an edge longer, actually cost less by a significant margin, or look better.

Choose your criteria.

I like the looks and, being a techie and "steel snob", the blades are appealing. I own a couple of these composite blades simply because of that.

However, I haven't noticed any performance advantage over some of my other knives and they certainly weren't inexpensive for what I got.

What advantage does the design actually have at this point as far as performance goes? What "higher quality"?

The Ti and wonder steel idea mentioned earlier would be an advantage - saves weight. Or a tough steel with a super hard steel could potentially be a good combo. Optimization of material properties could be achieved.

The potential is there if the bonding can hold up. So, the question of whether the bonding has proven to withstand various "out of the ordinary" stressing is of some interest, as well as how the bonding performs over time and cycling of stresses.

Well, you and nozh have a point, inasmuch as I doubt that added strength has anything to do with Kershaw's decision to manufacture laminate folder blades. I do believe that a properly laminated blade can be quite tough. (Fallkniven, anyone?) However I cannot see any task that would make a CPM-D2 folder blade fail before the locking mechanism or pivot on said knife failed first, even if run at very high hardness. No matter how much you wanna wish otherwise, folders are not fixed blades and can't use that much strength in the blade.

Besides, if Kershaw's D2 is so fragile that it can't be put in a FOLDER without laminate protection, then they better start recalling those Outcasts post-haste! They're not even CPM steel! They'll explode like hand-grenades if you try to whittle with them! OMG PLEASE THINK OF THE CHILDREN!!! :eek:

I will say, though, that I loved the blade on the one composite Kershaw I owned, the JYD II. Holy crap that knife was awesome. Probably the best liner lock I've ever owned, and the lamination did provide SOME rust protection to the blade, besides making it look cool as all hell. If only the clip didn't suck and wasn't bendy enough to cause the knife to fall out of my pocket, I'd still be using it today. :grumpy:

But yeah... decoration and a modicum of rust protection seem to be what it's for, at least on the folders, but I'm willing to pay the small premium for it just because I assume it's what KAI has laying around and so would only save a couple bucks if it WASN'T laminated. Plus it really does look swell. :D

Now if we saw a Galyean-designed composite FIXED-blade.... then we might see some real benefits...
 
I kind of wondered what strength a blade would have with a 12mm hole placed in it, but failures of those types of knives seem uncommon.
 
I noticed there was no denial re the space alien employment... pause for concern?

I'll be the first to admit that I love the way the JYDII CBs look - especially the 'unofficial' fuselage-detail grey G10 scaled one I have. They are fantastic values. Yes, it also cuts well - and I don't see a problem in it's use thus far. It - and the standard CB version - have been EDC back pocket adjuncts - for serious cutting. I like A2 and D2 steels. As my favorite blade metal is S30V, I would likely have grabbed nearly anything Kershaw makes with that metal. At present, my only such example from Kershaw is a Blur - and what a great knife!

I have been drooling over a Tyrade 1850 CB Ti (ZDP189) - it looks great in pictures. Pricey. Sadly, I found a LNIB BM 630 Skirmish I want more... and it cost less. Of course, as neat looking as the 1850 is - and the good press for the blade material - the 630 has an S30V blade - deal maker. Now, come out with a JYDIII in Ti and S30V, and I'm there!

I sure wish you folks (Kershaw) were back here... I miss you guys!

I don't think that is going to seperate unless you really want it to.
 
I like these Blades...they look Cool :thumbup:
My little Brother just got the JYDII & I got the ZT0350 & I like'em both :D

Thanks for the Great Blades Kershaw !!!!!! :thumbup: Keep'em comming(a few more lefty models please) :D
 
I usually try to avoid these threads like the plague, because they are counter productive. Kershaw has sold a lot of CB blades. I am pretty sure that as a member of 4 different knife forums some member some where would have a complaint about these blades falling apart. I have not seen any threads saying anything remotely bad about them. So unless the vast Kershaw Conspiracy has shut down all complaints about the CB technology I would say they work out pretty good.

When was the last time you needed to slam a folder through a brick? Or you needed to cut through a car door? These are the kind of "tests" that you are advocating? I may be "worshiping at the altar" but I really have no desire to take my knife to those "extremes". So whos altar are you worshiping at. Now back to your regularly scheduled trolling thread.
 
Hunter, I don't worship at anyone's alter. I like the Tirade and brought up a topic that I wanted to discuss. As you can see, I'm relatively new here and I was not trying to troll. Part of the reason (perhaps) that so many topics get recycled in new threads and therefore seem like troll threads might be because as a basic member I don't even have the ability to search for older, already established threads to read and get my answers from. If you reread the first four posts of this thread you will see that I asked my question and posts 3 & 4 were simply links to threads that if I could have used the search function, I would have easily found for myself and never needed to start this new thread to get my "ridiculous" questions answered. I have begun to really like this forum but frankly the one thing that bothers me is that I can't search and therefore avoid redundancy. Frankly it winds up hurting everyone that basic members can't search because there are probably twice as many threads that exist than need to. I'm sorry, not being able to search the forum hurts us all and sucks.

There are not that many quality knife forums on the internets to begin with, and this one is the best, and the biggest.

Pry open your wallet, become a paying member, and all will be revealed.:)

Best Regards,

what kohai said! you wanna buy a $85 knife? hell, you can't even throw down $10 for a paying membership!

ask a welder where the strongest part of steel is when you weld 2 pieces of steel together. the joint (welded part).

you like the blades but bash them? put your money where your mouth is.

i enjoy watching destruction tests, but i'm able to figure out that they are simply for entertainment. if you wanna abuse a knife buy a busse! a busse pricetag will run you $300-$1200!:eek: the busse in my sig will take the abuse you desire but will cost you $800+.:D

as for folders, i'll just cut with them. autopen- people on these forums remember what you say now. in the future you might want to sound less newbish or you'll be put on the list.:eek: buy what you like.

nozh-you made the list long ago
 
autopen- in my short time here, and my experiences in life, i've learned quite a bit. not as much as some, not too little. here is my non fan boy take on your question.:D

kershaw blades you're asking about are "made in the usa". that means they are made by americans (american jobs). use quality steel, 154cm/d2. use quality materials, g-10. use good locking system (liner, frame). and look good to boot (see my post with the pic.'s). i hear their customer service and warrunty are great, although i've never had a issue myself.

try to find another knife with all these attributes at that price point.

buy smart.

i can break any folder with my 23 oz. vaughn california framing hammer, but then that's not why i buy the damn things. i just cut stuff with them.

as for buying a membership, it has its upside. search function, saving you time. time is money. plus you get to support this great community. how many hours a day do you spend here? what is that worth. a gold membership allows you to sell the knives you don't keep for free! try listing one on an auction site see how much you pay per listing. plus the members you sell to here are like minded people who for the most part are civil and great to deal with.

plus all this knife stuff is supposed to be fun.:confused::D good luck with your search/buying.

Autoopen your original question was not ridiculous, it is a valid question but the whole destruction test thing just sets me off. Thats why my response was so venomous. It really was not helped along by a fairly infamous troll who really enjoys stirring the pot. So i probably should have stepped away from my keyboard and let it go If you were serious then I apologize if you were trolling it will all come out in the wash. Time will tell.
