Why so little love for CPM D2?

Basically, exactly what the title asks.
Used to be used in Kershaw's composite blades, but a couple years back they switched to "regular" D2.

I can't think of any major manufacturers making a knife in CPM D2, but other CPM steels see lots of loving.

What gives?
 
Oh.... well.... that'll do it every time!!!

Thanks for the info. Damned shame. What happened? Why are Crucible's other steels available but not the D2?

That's interesting because New Jersey Steel Baron still has a ton of it in stock. I I will check on this next time I order some steel :)
 
I didn't like it. Easier to sharpen but IMO it dinged a lot easier than regular old D2.
 
Crucible discontinued it because it wasn't popular. CPM D2 didn't offer enough of an advantage over ingot D2 to justify its increased cost.
 
I thought PSF27 was all kinds of better than ingot D2. It's not my preferred steel but it does a lot of things very well.
 
Niagara Specialty Metals is the current producer for CPM spec-ed steels, including CPM-D2. http://www.nsm-ny.com/index.cfm

One should get similar perform from a good ht of either CPM-D2 and Psf27. Also, without huge ingot D2 carbides, these 2 steels similar to CTS-XHP. A slight bit more wear resistant but less corrosion than cts-xhp.

How's your testing going with XHP?
 
My limited informal tests... CTS-XHP just a slightly less wear resistance than Elmax, 20cv/m390, D2 but over all it has better edge stability, especially impact toughness is roughly 30-50% better than listed steels. I think hxp ~11% vs others 16+% carbide volume and smaller carbide size (because lower CV, less aggregating) is the key reason for high edge stability (relative to listed steels). At 62-63rc, it's only slightly lower impact toughness compare to aebl at 62-63rc. Tested via 2-3" distance wrist flick chop into hard materials: bone, african blackwood, nail.

Here is one D2 knife from Enzo, Birk 75

CPM D-2 is alive and well. We don't sell a lot of it, but we stock it and can always get more slabs from Crucible Industries to roll into sheet.

OK, with that being established, it's available and just not being utilized.

So let's go back to my original question.... why the hell not?
 
I wish I had the answer. 154-CM is one of our highest volume grades and CPM-154 has a very loyal following from custom makers. D-2 is also a grade we sell quite a bit of, but CPM D-2 never really gained any traction. We bought CPM D-2 because we knew there are people who love it, and we will always carry it. Who knows, maybe some day it will take off. That's what happened with CPM 3-V. We had whole heats sitting in our yard for a couple of years and then all of the sudden it starting selling like crazy. We actually ran out for a short period of time. It has become a nice grade with a lot of support from the knife community. We'll continue to listen and hopefully give everyone plenty of options.
