I was wondering how is CPM s90v steel? What steels can it be compared to and what are the pros and cons of the steel?
 
The steel has been discussed in some depth, you can use the search feature, but in short: it is a high wear resistant steel that is good for cutting. It has large vanadium carbides that produce the high wear resistant characters.

Steels with similar composition are available CTS-20CP comes to mind. Look at Phil Wilson's customs. He does exceptional work with it. (He posted on the Spyderco forum about his South Fork design with spyderco and intended use)

Hard to grind and hard on machines, so that is an increase in price.

Not suitable for large camp knives or choppers due to the large carbides IMO.

Forgot to ad, M390 can be close to the same edge retention and probably CPM-M4 (not as stain resistant). As well if done right. I doubt one would experience significant edge holding difference between them if all are done properly and in day to day use. Under testing conditions one might find one performing better by some margins.

It's Excellent, very stain resistant, very wear resistant, and a very aggressive cutter.

CTS 20CP is Carpenters vers of S90V.

If you do a search you will find tons of info that I and a few others have posted here, reviews etc.
 
Thanks for they help you guys and what steel would you prefer over it for EDC or is it perfect for EDC?

Depends on ones use really, but yes it's a excellent EDC steel and very hard to beat.

Just to clarify----the carbides are very small and that is one of the main advantages of the PM steel grades. they are on the order of 2 to 4 microns as compared to ingot steels who can have carbides that range from 10 to 20 microns or larger. Phil

Thank you for the correction Phil

I actually just read a Msc paper on carbide size and powdered metallurgy that gave me a better understanding about how fine carbides actually are in this process. It helps a great deal to see the pictures.
