I'm a big fan of D2 in general, but I have heard some great things (anecdotally) about the CPM D2 steel in particular.

So what makers are putting out knives in CPM D2 currently?
 
Kershaw does some great things with CPM-D2 in their composite blades:thumbup:

Tom Krein also uses it for some of his knives, some of which I own and really like!

I use standard D2 for a lot of my knives, made by Bohler in Sweden. I've been meaning to pick up some CPM-D2 but I don't see it around too often.

Benchmade uses is in their 710 as well as a few others, I like it quite a bit.

I think the OP is asking specifically about CPM-D2, the Crucible Particle Metallurgy version of D2. The stuff Benchmade uses is regular (non-CPM) D2.

Kershaw, as already mentioned, is going to be your best bet: their regular production composite composite blade knives (Leek, JYD II, Rake, etc.) use CPM-D2 on the cutting edge. Also, Spyderco did sprint runs of the Military and Paramilitary in CPM-D2. You'll have a tough time finding the CPM-D2 Military, but if you keep an eye on the Exchange and on "the big auction site", you should be able to get a CPM-D2 Paramilitary pretty easily and at a pretty good price.

Kershaw produce several knives with composite blades with CPM D2 on edge - like Rake (which is very sexy knife). What is important - they do pretty good HT for it, I would say CPM D2 is their best performing steel so far and price are very good too. On my test Tyrade with composite CPM D2 slightly outperform Spyderco Military CPM S90V and same or very little behind Spyderco CPM M4 Mule.

Thanks, Vassili.
 
I wouldn't suggest it outperforms S90V. Crucible wouldn't and hasn't stated that either. Quite the opposite in fact.It does give regular ingot D2 a performance upgrade in ease of sharpening,Finer carbides, slight toughness increase, and finishes better ,and easier than ingot D2.

It's like CPM 154 to 154cm. A noticeable and worthwhile improvement from this users perspective. I have no idea how the balance sheet works out for knife manufacturers though.


S90V product page includes comparison to D2 in a couple of steel attributes. Note S90V is virtually as tough as D2, hugely more wear resistant, more corrosion resistant, etc. Performance figures for CPM D2 should be a little higher but not enough performance increases to place it above S90V.

Nice chart from Niagra With CPM D2, CPM s35VN etc. It has wear resistance and toughness attributes compared, but not corrosion resistance. Still pretty cool. :)

Yes, but clearly you've forgotten about Crucible's conspiracy to lie to their customers in order to push an inferior steel(which few makers even use because it's frustrating as hell to grind) on the market:rolleyes:.

Honestly, anyone with a waterstone(not diamonds) and about 6 hours of free time can tell which one is more wear resistant.
 
I was under the impression crucible stopped producing cpm-D2 , someone correct me if in wrong but I remember hearing something along those lines after the d2 para and Millie came out .

Well, Niagara is listing it. Does that mean it's a stock item? I have no idea. The owner/boss of Niagara stops by here now and then. Perhaps we will get the answer.

:confused: Conspiracy?

As for the original thread topic; I love CPM D2.

CPM S90V is more wear resistant, some people can not understand that edge holding and wear resistance is different thing. Wear resistance is good to resit grinding, but not stay sharp. Huge content of carbides weaken steel mitrix, like too much sand weaken concrete. So all those V steel may be good for tank garage floor to not to be wear by tracks but not for knife edge.

Not being able to keep intellectual discussion some people desperately try to turn it to some kind of word circus, bringing everything (like conspiracy etc) to hide their inability to speak on the matter, having very limited or no any personal experience with discussed topic, rather then second, at best, if not third or fourth hand data reading something somewhere.

I cut 200 times 1/2" manila rope and this is only source of my conclusion that Kershaw did very good job on their composite blades with D2 on the edge and it in deed outperform slightly CPM S90V and show same results as CPM M4 (and it is more corrosion resistant then that one).

Thanks, Vassili.

What in the heck are you talking about...... :rolleyes:

That has to be the most uneducated statement I have ever read regarding steels.

By that statement you are implying that one cold take a knife made out of pot metal and it would hold an edge forever.

Leaves to go beat head against the wall......

Aaannnnddddd off we go!

I like D2 just as much as the next guy, but it does NOT outperform S90V.

Well when someone makes a statement that makes no since at all and goes against everything that is metallurgy then yeah I beat my head against the wall.

I started laughing when I read that....

Yeah, D2 will never outperform S90V, not on this planet anyway...
