Shootout: CPM-S90V vs CTS-20CP

I am curious about the sharpening as well. S90V requires a good bit more effort to get razor sharp (IME) as compared to M390 or 154 CM or ATS 34...Won't hold an edge as long...but the other steels are easier to sharpen.

Thanks again JIM!!!
 
Thanks for the test!!!

I guess to all you peeps out there....if you missed out on the CF S90V Para, make sure you try and get a CTS 20CP para.....despite it's lack of carbon fiber beauty, the steel stacks up well against the s90v one.

Great test!
Thank you!

"Doing it well below the cost of S90V is even better. This is a breakthrough"

The price was really close? It matched S90v in this test. Do we know for sure it will be cheaper to produce?
S90v is hard on tools (Its hard) is this some how easier on tools but holds the same edge?
I have to think some of the xtra $$$ for the S90v model was the CF over the gray G-10.
Or am I the only one?
Mine should be here Wed/Thurs.... Yea.........Light Gray............

20CP seems to be easier to work with. :)

It will be harder than those steels due to the alloy content, but with more effort it will get extremely sharp.

Thanks. :)
 
Thanks for all of the testing and review Ankerson! I am glad Carpenters' steel performed so well. Crucible having a quality competitor can only be a good thing for us the users/knife junkies.

I looked at the alloy content awhile back and it looked like it had a lot of promise. :thumbup:

I think the custom guys should be able to run it pretty hard too, harder than S90V, but time will tell on that.
 
Thanks for the great testing. Very pleased that 20CP performed so well. Now I just hope one of my relatively late pre-orders comes through.
 
I have them sharpened up for the EDC videos, that's 320 grit EP stone to show how really agressive they are. :)

These steels are EXTREMELY agressive.
 
Here are the 320 Grit edges ready to go for the EDC videos. :)

Thanks for your testing, Ankerson. Very cool results. I'm glad to hear that there is a competitor to CPM S90V. Hopefully this means we'll see more steels of this caliber so those who miss out on certain sprint runs can still obtain and enjoy the steel.

Do you think you'll carrying the CTS version more than the CPM? :p

Can't say, it will be like a coin toss thing, I like both knives.

I am really hoping to see more of this steel in other knives, but only time will tell on that one.

I think we are seeing history being made right now as this steel could be a landmark steel for the knife industry as it was developed for the knife industry by tweaking S90V for use in knife blades.

Is that what Carpenter says? I know they promoted a few steels for use in knife blades, but I was under the impression that only a select few like S30V, Aogami, and Shirogami were truly designed for use in cutlery.

That's the talk around the water fountain so to speak.

That's what Spyderco is saying exactly, it was developed for knife blades.

Not to be contentious, but that doesn't necessarily mean knife blades, as in personal cutlery. In fact, I think it was you, Ankerson, who reminded me that many steels were developed for industrial machines to cut plastic.

Close, most are used for dies or injection molds. The high wear resistance prevents dimensional changes in the mold so it can be used longer.

I say the plastics industry as in injection molds, cutting etc and they have to be very corrosition resistant.

That's what S90V was made for, CTS-20CP is what Carpenter came up with leaning towards blades improving on the workability of S90V while keeping the same or close to the same wear resistance and corrosion Resistance.
