CPM154 vs S30V

IMO crucible will replace S30V with S35VN...

...and CPM154 will take a back seat -- pure speculation . .

I would totally agree with that, :thumbup: :cool: :thumbup:

...I think we will all come to love S35VN,

...and it will become the Super Stainless Steel that makers choose.



But it's the High Carbon CPM-3V that looks like the best performer to me. :eek:

This post reminds me why I won’t buy any knife right now with “CPM154”.

Most people don’t know the difference between the powdered version and the regular. This includes dealers. I’ve seen too many knives for sale being tagged CPM154 that I know very well are 154CM.

If the blade isn’t marked CPM154, I’m not buying it.

Speaking of S30V, whatever Strider does to theirs is perfect. It’s easily the best performing S30V I’ve ever tried, much better overall performance than some of the other high end brands.

Funny. I seen a post the other day where a guy was complaining because he bought a knife that was supposed to be made of ATS 34 and the blade was marked CPM154 when he got it. He ask why the company was down grading. He was clueless that they were the same. There are a lot of people tha bite on the marketing ploys between the different companies, for sure.

ATS-34 and CPM-154 aren't the same.

ATS-34 and 154cm are the same.

CPM-154 was an upgrade from ATS-34, not the same or a downgrade.

I think some might even confuse ATS 34 with RWL34.

RWL 34 is really really good stuff from what I have read.

At the end We are spoiled for choice, S30V or even 1095. All good steels and someone is always trying to improve on something. Great for us but for a beginner in knives it can be a headache! Either way, I dont see one is going to replace the other, but I dont know the market. My experience with S30V has been good. I only have 154CM so cant compare it to CPM 154CM.

Why would you want to spend more on a custom maker's version of a large Sebbie than you could get a large Sebbie new for? The CRK warranty is legendary, too. Heck, my CRK/Wilson Combat 'StarTac' Umnumzaan was $430 delivered... keeper of the first order. Of course, if you want CPM154, you're out of luck!

I already have a small Sebenza and Wilson StarTac Umnumzaan, so I do not want a large Sebenza because it is too similar to the Umumzaan.

What I really would like is a Medium Sebenza with about a 3.3 inch blade, but this knife is not made, so I am looking for alternatives and the SFC C-1 looks promising.

The Lg. Sebenza is very different then the Umnumzaan.

S35VN is a bit easier to work with than S30V. The biggest advantage is the toughness over S30V. Ive read a few posts about complaints with S30V's brittleness, the S35VN supposedly remedies this.

3v has sick toughness, but relatively low edge retention. Try 10V or go crazy with 15V if you want some great edge holding! But good luck trying to sharpen it.

I tried to get my hands on some S35VN bar stock this week, it was sold out in the size I needed. So I got some Elmax instead. Word around the campfire is its got better toughness than S30V with a little less edge retention. Should perform somewhere between CPM 154 and S30V.:thumbup:

ELMAX is better than they say it is, HT it to around 62 RC and test it.

Okay, if you say so???

It's a different knife with different uses. I'm saying you probably won't feel like you have two of the same knives if you do get a Lg. Sebenza. Unless you're saying you already have a 3.75" titanium framelock, what do you need another for?
 
If you're a CRK fan, I think they're different enough that they won't interfere with each other. Ultimately though, they're two large titanium framelocks with similar shaped S30V blades.

CPM-3V rules the non-stainless camp IMO, especially for big blades. Heat treat is critical for good edge retention -- for some reason my Fehrman blades do well in edge holding -- small sample size though . .

3V -Good for big blades, chopping.
10V -Great for smaller blades awesome edge holding.

But I'm a bit partial to M4 in non-stainless. Gives a great balance between toughness and edge holding.

But IMO if you want great edge retention stick to S90V. Almost as good as 10V but stainless.

Wish I could get my hands on some S110V!
 
I've worked with CPM 154 (still do) and it's outstanding in toughness and edge holding. Another winner is CPM S35 VN. I did some extensive testing (which is still on going) and it is an excellent steel. The CPM S35 VN is said to be an improvement to S30 V. Same as CPM 154 is an improvement to 154CM. I don't think you'll see either of them discontinued.

On a purely subjective level, having owned various ATS-34, 154CM and S30V knives, perhaps it's geometry, perhaps it's heat treat, but my S30V knives LIKE to cut. :D

It's that toothy working edge that S30V gets that makes it cut so well.
 
I have a question... why don't more production knives have CPM-154 as an option? The major player used to be Buck.. they had a couple in CPM-154, but now its only the 110. Kershaw has one also, but that is it.

Does CPM-154 cost significantly more then S30V?? I would love to have more options with CPM-154 without having to dish out a ton of money for a custom. And.... even if you did want a custom they are hard to get.
