not sure if this is the right place but here goes, why did kershaw choose to laminate the d2 in 154cm?it seems expensive to put On a knife even though it serves no better than 420j?
 
Did you really register on bladeforums yesterday and decide to make a post like that ? Seems a little suspicious to me. Seems like you are trying to cause problems, I hope not , but it seems that way.

im not trying to start anything I love kershaw Ive owned over 20 of their knives. they are one of my favorite companies. it just doesnt make any sense to me and im hoping somone can help me out.
 
well there is a whole lot of difference in 420J and D2 tool steel. I am no expert but they are not close.

I know that but what im getting at is why would 154cm
(a premium knife steel) be used where 420j would be just as good and much cheaper? I trust in kershaws knives 100% but I dont understand why they chose to laminate it in154cm im sure theres a good reason but its beyond me. thats what im asking
 
What he's looking at is, it's the steel at the edge that counts. Using a premium steel to cut with makes sense. It would seem that the steel to which it is affixed wouldn't matter -- wood, plastic, titanium or S30V, it's only there to carry the edge.

In some laminates, for instance, the core steel is a premium steel like VG-10 but the sides attached to it may actually be 420J2.

Can anyone explain why Kershaw uses 2 premium steels?

Well, because the initial run of Tyrades that came with anodized titanium handles, carbon fiber overlays, and premium blade steels was supposed to be an all out knife. It was a limited run and was intended to dazzle. The more recent runs with G-10 handles were made using excess blades after the first project in order to make a more affordable version available to Kershaw lovers like us:thumbup:

What he said! :D

Also Kershaw uses a welding bond process now to make composite blades, unlike the laminating of the SG2 JYDIIs and Blurs. The Tyrades aren't laminated. 420J is used in many laminations. Most often this lamination is over ZDP-189. 420J happens to bond very well with ZDP-189 which is one reason it used for laminating. The other reason is that 420J is quite soft and flexible while ZDP-189 is not. When a blade is laminated the softer steel protects the harder steel from flexing and breaking if any lateral force is put on the blade.

The bonding process uses a copper weld to attach the two seperate pieces of steel together to form a solid blade. Again, it is important to find steel that matches well and can form a solid bond with the weld. In the case of Tyrade, Kershaw could have used a different type of steel. Like JonnyMac44 said, the original Tyrade was a Ti framelock handle with carbon fiber imbellishment overlay, a premium cutting edge in CPM-D2 with a beautiful etch to contrast with it's matching steel. Now Kershaw could have used some kind of other steel like the Sandvik 13C26 they were using at the time of the original Tyrade's inception, but instead they decided to use a premium steel in 154-CM to pair with the CPM-D2. The reasoning was that the Tyrade was really made for Kershaw collectors and afficionados and Kershaw wanted to produce a knife that was made of strictly "top shelf" materials, thus we have a spine of 154-CM and a cutting edge of CPM-D2. It's one hell of a knife and both versions are actually quite affordable for what they offer.

if I misread you , I apologize , I have been a collector of kershaw knives for 25 years and I really thought perhaps that you had just joined under a new name to cause problems, it happens. Anyway welcome to bladeforums. Sorry I jumped to conclusions.

I do know for a fact that not all steels bond ideally to one another.

That being said, Kershaw wanted to pioneer the technology with two premium steels in a premium model, hence the Ti Tyrade w/ Carbon insets.

For latter models, Kershaw used 14C28N as the spine of the D2 Leek, and 13C26 for the JYDII spine, to keep the price down.

its cool I understand how it could seem suspicious but i joined the other day then oredered a tyrade, and wondered why 154? but now it makes sense thanks to you guys!
 
I know the answer...

They expect you to keep it for a while... and sharpen it a lot. When the D2 runs out, you have another great metal - and - a serrated blade of sorts.

While I have some Kershaw folks here - I love my Ti/SG-2 JYDII. Sadly, an 1850 Tyrade Ti/CB (154CM/D2 - like we've discussed.) is still available for just less than $200 new - is that too much? I was trying to get another Benchmade or two, I know, banish me - dull my Blurs, and that much would end my knife buying this year. Opinions? The BMs were the 615 mini Rukus and maybe a 420 Resistor. Thanks.

I somehow doubt that is the reason, no offense. There is a copper strip that bonds the two and would make a terrible transition. The exposed copper would just fold over and be useless.

I won't post what I was going to say to be nice, but I had no problem understanding the question, and it seems like a reasonable question.

I'm reasonably sure he was kidding.
