"CPM S30V was huge step back from CPM S60V" Good grief, did you really type that rubbish? :rolleyes: CPM 440V AKA S60V was a totally different steel to S30V. It was a much more difficult steel to sharpen, far more fragile and really not at all suited to even a moderately hard use knife. Only tip I ...

I'm sorry I returned too late to catch the inflammatory political content. ;) Yes, pointing to the testing you've done and demanding I produce mine in order to earn my right to an opinion is one way to respond.... But I have done extensive testing of my own and my results for S30 are the same as yo...

OK, Vassili, but do you agree with the other posters that S30V should be "toothier" than ZDP-189, because the latter is finer grained steel? Well, CPM is made by PM process, so this tooth can not be bigger then 1-2 micron. Also there are not too much vanadium carbides in there V=4%. So I do not thi...

HA! Thank you for that. :D I'm a customer and I've used both steels. The superiority of ZDP that you mention doesn't show up in my uses. Neither does the inferiority of S30. You've clearly found the better steel for your use though. "Then you must only have used ZDP with incorrect girly heat treat!...

dbcad, the edge that was sharpened on a knife isn't an indication of steel quality. I recently took a new FFG byrd and sharpened it until just the weight of the knife blade resting on my finger has the edge beginning to separate the skin and start push cutting in. Does that make it a better steel t...

Well let kind of make clear about what sharpening we are talking about. I use DMT D8XX, D11C, D11E and Green Rouge to make any steel whittling hair an about 5-15 minutes. Does not matter what steel it is ZDP-189 or CTS-XHP or D2. Using this methid all steel asr the same. Now is it possible to say wh...

Well, I am old enough to see that this idea "Always Compromise" is simple universal excuse for slaker. It is obvious that it is very easy to find two product one of which is just way better in all points. Just because in one case job is well done in other they just throw it over fence.

Some of the posts about this steel have given me the impression that it is difficult to sharpen. I'm talking about touching up/restoring the edge on a Sharpmaker, not reprofiling, or anything like that. How does it compare to VG-10? It is usual complain about any new steel came to market, especiall...

Not everything is about maximum edge retention... If that were the case then every manufacterer would use S90V, ZDP 189, S60V, etc. S30V was a good comprimise of edge retention for much better toughness and corrosion resistance. The purpose of S30V was never to have maximum edge retention but for a...

By CATRA test which is standard for industry. By my own tests, by quite a number of reports on forums.

Thanks, Vassili.

What are the pros and cons of these two steels and how do they compare. CPM S30V is US made by Crucible entry level PM steel which does not perform well, it was pushed very hard to be on the market 7 years ago as a replacement of CPM S60V (which was really good), but it is hard to hide for so many ...

The Marathon kept horrible time. The Omega Bond and the Rolex Sub keep about +2 min and -2 min per month, respectively. I have a Rolex GMTII that keeps 1 second per week if I am on my usual routine. The Traser of course keeps essentially perfect time, but has no soul whatsoever. I just got Seiko Su...

'zackly ;) But even then, you're comparing Sypderco's HT to Spyderco's HT, and there is also the possibility that different grinds or edge geometries would vary the results. I know you know that...but I think it's worth remembering these things. :) :spyder: Let me reiterate this again - blade geome...

But - the blades were heat treateded differently, even when the steel was the same; the blades came from different manufacturers; the blades had different grinds. You are testing finished blades, not steel. It is either pure misunderstanding or misrepresentation to suggest otherwise, no? Sure, as I...

Well, unfortunately I guess you are not going to do yourself any testing. As well as anybody else. I am crying for this for several years, but seem like nobody want to do anything harder then typing on keyboard.

Thanks, Vassili.

Hey Vassili, I agree with you that specific models of knives should also be tested for performance. However, it would also be nice to see tests of steel vs. steel that are in the same configuration(geometry, and other aspects). Your efforts are appreciated and your test results are also quite infor...

No one is trying to say your tests are in vain, I enjoy reading your posts and seeing the results of the cutting tests. But with any scientific experiment, you have to have a control, and results must be able to be replicated. Different heat treats, different steels, different manufacturers, differ...

The basic question posed by Ken & Vassili is simply this: Was that S35V sample heat-treated in a similar way as that S30V sample? If it was, then Vassili's results have validity. If they were heat-treated differently, then we have two variables either of which could have influenced Vasilli's result...

Couple of things: If I claim that I cut strings with 2 knives both with S30V and one was Brand X with a wood handle and one was a Brand Y with a G-10 handle and one out performed the other, could I then proclaim that the handle material is to credit? Then could I force the world to provide data to ...

That is fine, but understand that your statements are misleading as they imply that there is a direct comparison between the steels and that simply is can not be backed up with the data you have shared in this thread. Your statement, "....stay away from CPM S35V wich perform worse then CPM S30V" im...
