I was wondering if any of you have any blades with S30V and CPM S30V. And, Can you tell a big difference in edge retention, and ability to Sharpen ?

Is there a difference in Slicing , or cutting between to 2 ?

Just wondering

Please advise......

Thanks
 
Whoops , Sorry......I was told different.....COMPRESSED POWDERED METAL "CPM" - That's right, isn't it ?
 
HAHAHA !! That must be why he got fired !!!!!!

Although, The majority of the Metals that we worked with was Ductile Iron, and Brass, Bronze, etc.
 
Interesting, how a simple irritation leads to a long topic.

Well the difference between CPM154 and 154CM is nearly the same as between RWL34 and ATS34. :cool:

Metallurgy is a broad field, and unless your friend specializes in blade steels, he may not be familiar with the differences in all the alloys. I work with a number metallurgists, and I know more about blade steels than any of them. The fellas I work with specialize in Titanium, Aluminum, and structural stainless steel, but not blade steel. Blade steel is a specialty all in itself.

So, as others have said, "CPM stands for Crucible Powder Metallurgy and S30V and CPM S30V are two names for the same beastie."

Well, I managed to avoid posting a "dummy" comment but did get something out of this thread by reading your post and googling up some information on RWL34, which was interesting reading. :)
 
CPM = Crucible Particle Metallurgy
S30V and CPMS30V are one in the same. Some knife production companies took it upon themselves to shorten the name to S30V.
 
I know this is an old thread, but I understand the confusion. I have a knife labeled s30v and another labeled cpms30v and they are definitely distinguishable. HOWEVER, they are from two different companies... Heat treat is key.
