What is the best performer in your opinion for those that have or used both?.
I know the cpmD2 should be better in theory but is it better in use comparing the knives side by side?.
 
Presumably you mean s30V.
I personally am not entirely satisfied with the edges I can get with S30V (mind you, I'm not that good at sharpening anyway). While VG10 and D2 have served me well, though I don't think I've ever used CPM D2.

The issue is, of course, I've never used the exact same blade geometry in each steel type, but personally, I'd go with the D2 ;).

No just what i said.
There is a D2 and a cpmD2 avalible from what i have read cpm version should have several advantages over D2 just wanted to know how much so in use and maintence.
I have a para in S30v i like the steel and have several knives in it i can get a scarry edge on all but a benchmade activator which i need to reprofile.
Try a diamond guide system if you havent already although a sharpmakers all you need to touch up to razor sharp.
 
I dont have any blades in d2 or cpmd2 but i know d2 is full of large carbides which makes me lean towards cpmD2.
 
Damn, these message boards need spell check and grammar check. Some posts are just too painful to read.
 
I think I've heard from Sal that he gets CPM D2, and it should be stamped on the chosen blades. The differences that I've read about are that CPM D2 of course is cleaner and more finely packed than the D2 that any john smith can put out. It should take a finer edge and hold it longer than the "standard" D2.
 
Everything i have read so far doesnt show much or any diffrence in use wear wise.
Would it be easier to sharpen the cpmD2?.
Also if anyone has both knives.What one micro chips/chips easier if you can tell?.
 
CPM D2 seems to be more corrosion resistent than ingot D2 in my experience. My regular D2 knives will develop rust and pitting in pocket carry (I tend to get wet at work sometimes, and it isn't always just water) but I have not had any such corrosion on my CPM D2 Military or Paramilitary.

CPM D2 seems to be a bit easier to sharpen, but my perception of that may be skewed by having to totally rebevel a couple of Queen D2 blades to thin the edges to something reasonable. I haven't really noticed any difference in edge holding in side-by-side use, nor have I noticed any unexpected chipping with either.
 
Crucible Particle Metallurgy (CPM) is a type of metallurgy that allows fine-tuned manufacture and engineering of the particles of the steel, enhancing its carbide structure and several other significant aspects that result in a cleaner (that is, more evenly dispersed) composition of elements and leads to a more consistent performance from the blade as a whole. As such, the CPM D2 is a variant of the standard D2 tool steel that is used with a more consistent, closely engineered process.

Standard D2 is just that---standard. It's made, heat treated, etc., in the traditional process. Either are excellent for a working knife in my opinion.

God bless.

Just for clarification, the Military and Para were only done in CPM D-2, not standard D-2. The tricky part is that some websites don't bother mentioning the CPM part.
