I see where benchmade uses this for there blade steel on many of there knives. Where does this type steel stand as far as AUS8, VG-10, 440C and CPM S30V?
 
S30V is what God what use in a knife if he made one. ATS-34 and 154CM are the "super steels" that are a step below it, but a step above aus8, 440c, and vg10. They are also stainless.
 
If GOD were using a knife, it would be a large Bowie. 52100 or L6 is the likely candidate there as S30V is too easily breakable in a large knife, and a huge pain to sharpen. For small knives, it does OK. ;)

Sorry, I believe God uses a 'terrible swift sword' 154 cm is a good steel, it is only slightly different than ATS 34. Benchmade does a good job with their heattreating. Go ahead, you'll be fine.
 
Actually, I place VG-10 above S30V.

But 154CM is just below S30V.

440C is hard to place at all because it seems to be either extremely good and on the same level as 154CM, or it is not very good at all and on the level of AUS-6.

Good luck,
Allen.
 
You will probably never notice the difference. As long as the knife is made from quality steel, is properly heat treated, and has a useful blade geometry, it will cut. It is more important to fit the knife to you and your use, then to worry overly much about the minutia of its chemistry.

N2S pretty well nailed it. Many of us have steel prefferences. Mine is BG42 first and ATS 34 second, with S30v around 420hc. I'm dissappointed with it.But that's my opinion and experience.

154CM, VG-10, 440C and S30V are very similar in hardness and the edge retention and overall performance will be very close, you would want to be looking at performance very critically to notice a difference. AUS-8A is significantly softer and most people can tell a difference in edge retention.

On what do you base your opinion? How many factory knifes with each steel do you have? How many custom knifes with each steel do you have? What kind of tests have you preformed?

I think the operative term here is "very similar" and that's very true. With the modern high tech steels, the differences are usually not noticeable by the user. They are more a topic of discussion than practicality. It is also true about the similar hardness and edge retention. In my personal experience, however, both VG-10 and S30V are a little tougher with the normal heat treatment. I would imagine Cliff would agree with that from his many knife tests. That means they will endure more abuse from actions unrelated to slicing than the others. They are a bit more expensive for that reason. VG-10 is available in Japan and used in Japanese made knives while S30V is American and used in American made knives. I don't like using the term "better" or "worse" with steel since it can only be better or worse in a given one of many parameters. But I would say VG-10 and S30V are more versatile than the others if not better or worse.

In order to improve the hardness parameter, you would need to go to some of the very exotic Japanese steels which tend to be brittle in a knife blade (I know of some 440C's that are too brittle to be used on a knife blade for that matter.) To improve toughness you would either need to temper stainless steel down to a lower hardness or choose a carbon steel. To improve corrosion resistance would be easy. The move to AUS-8, as an example, would do that. Otherwise, I think VG-10 and S30V are pretty hard to beat as knife blade stainless steels from an overall perspective. If the knife is intended to be abused I would choose something else. If it is intended not to be used but to be admired I would go a different direction as well. But these two are quite versatile.
 
Crucible has just uped the ante by making 154CM via the CPM process and adding some vanadium

CPM 154CM- I have made a few knives from it and it is great.

Next time he is sending a rain of fire!!!! :(

BG-42 can get up to 64 HRC, CPM-90V and S30V can both push well past 62 HRC.

That is probably the most pragmatic statement made for the everyday knife user like me. Now for the guys that design 'em, make 'em, and work with them everyday in intimate ways I am sure many more factors come into play. But for me, who cuts with 'em, and sharpens 'em, and maintains 'em the rest is indeed minutiae. ;)
So, I just get one outta each kind of steel by the major makers and use 'em all:D . Why in the world would God need a knife when he can watch us toy with 'em?

Oh freaking aweXome!!! I can't wait to check out some of that new 154cm. That is going to be some really sexy stuff. Do we know if any production companies are going for it yet?
