Is Case "CV" D2, 1095, or something else? I know I have seen it on this forum somewhere, But I can't find it. According to the search feature, there has never been a thread containing "case", "D2", or "CV. I believe I also read that Queen produces the CV knives (or perhaps just blades) for Case. True?
 
Pretty damn sure it's not D2. That stuff is pretty pricy, and a LOT harder than what Case uses, at least if it's heat-treated right.

I'm guessing it's either 1095 or something comparable. Like a lot of makers these days, they don't state the actual steel used, so that they can save money by buying whatever they can get a good deal on.
 
IIRC CV stands for Chrome Vandium, and simply indicates that those elements are present in the steel. It is a carbon steel. It's definitely not D2.
 
And, it's definitely not 1095, as those elements are not in 1095. I would guess something closer to 50100B.
 
May be totally wrong here, but I thought Case only used "CV" in conjunction with the label "Stainless Steel"... I think the CV is what Keith M said - Chrome Vanadium... elements to assist Stainless Steel like ATS-34 or 440C become a little more wear resistant and stay stainless?

From Joe Talmadge's Steel FAQ: (http://knifeart.com/steelfaqbyjo.html)

0170-6 - 50100-B These are different designations for the same steel: 0170-6 is the steel makers classification, 50100-B is the AISI designation. A good chrome-vanadium steel that is somewhat similar to O-1, but much less expensive. The now-defunct Blackjack made several knives from O170-6, and Carbon V may be 0170-6. 50100 is basically 52100 with about 1/3 the chromium of 52100, and the B in 50100-B indicates that the steel has been modified with vanadium, making this a chrome-vanadium steel.

That's the only class of steel mentioned with both chrome and vanadium. The comment "but much less expensive" leads me to agree, 50100 (or something similar) is probably what Case is using.

Case states on their packaging of the CV knives that they are not stainless
 
Gryffin, this is the most logical explanation I have seen, thank you all for your input.
Being a bit of an obsessive compulsive, anal retentive type, I just had to have something to cling to.
 
For the record, Case's CV is pretty good steel. It's easy to sharpen, yet holds an edge a helluva lot better than their crappy Tru-Sharp Stainless.

In that way, Case CV reminds me a lot of the steel Schrade used to use in their Old Timer knives (not the stainless Schrade+ used on the Uncle Henrys), only better polished.

I just wish Case would use it more widely; that Tru-Sharp stuff is embarassing.
 
I have heard from several sources that Case Cr-V is indeed 50100B (or 0170-6, take your pick).
 
Many folks believe Case CV steel is 1095 with C and V added.
 
It is 1095 with small amounts of Cr and V added (HRC is 55-9), as per a Case rep.

My guess is that it is the same as or very similar to Camillus's 0170-6C and CS’s Carbon V.

Yes, you're totally wrong. :p ;) :)
 
I hope this doesn't seem like "hijacking" the thread, but I sometimes wonder why slipjoints don't seem to use some of these wonder steels (e.g. VG-10, CPM SV30) which are rust-resistant, AND, hold an edge well. Is it a cost
issue?

6 series steels are CV steels. 5 series steels are Chromium steels. I recall seeing a post somewhere where someone sent a case cv blade out for analysis and it came back 6195.


The following is basic numbering for AISI / SAE carbon and low alloy steels:
1 - Plain carbon steel,
2 - Nickel steel
3 - Nickel / Chromium steel
4 - Molybdenum steel
5 - Chromium steel
6 - Chromium / Vanadium steel
7 - Tungsten / Chromium steel
8 - Nickel / Chromium / Molybdenum steel
9 - Silicon / Manganese steel
