CPM154 and the future

You are thinking of 154CM and it was jet engine fan blades.

CPM 154 was developed as a knife steel for the custom makers.

From what I have read which could be wrong, CPM 154 and 154CM are virtually the same thing?

Same alloy, yes, but nowhere near the same thing. Cpm154 is a powdered steel which has higher toughness and takes a finer edge than 154cm. There should also be a slight bump in edge retention over 154cm.

Buck has made runs of the 110 in 154CM and it's a great steel.If Spyderco made a Para2 with that steel and Tiger stripe camo scales,my wallet would be slimmer!:):thumbup:

Paul Bos is a master with heat treating steel, that is one reason why Buck knives are such good cutters.
 
I would snatch up a FFG manix with cpm 154. I had a manix briefly but just didn't dig the saber grind.
 
Thanx RevDevil,

Some threads take longer than others to get to. Most don't need anything from me as the locals have much knowledge and can repond to most q's. Sometimes You guys are hard! I do have a day job, and of late a 2nd job.

I'm not opposed to CPM-154. We did a lot of tesing with it. I thought I remembered doing a short run of something, but it's vague. In testing, it did well in all areas. I think it was run over by the new S30V, which was a specific knife steel.

Crudible and Niagara do a fine job with the steel. I can check with Bob and see the current status.

Just about anything that we make out of it will take a while. Golden mfg would be good and the Milli, Para or Nat5 would work, but all are behind. We can put in in the Yojimbo. That would require Mike's consent. But it's behind as well. A mule team might work, but there's 2 ahead of already in process.

Over the long term, I'm hoping S30V and S35VN both get cycled out of the knife industry in favor of CPM154 as the standard 'high end stainless cutlery' steel. For the majority of folding knife uses, the extra toughness provided by the S30V isn't really needed - CPM154 is plenty tough. CPM154 builds on a solid foundation (154CM) and adds a little extra toughness and edge retention into the mix with their powder metallurgy process (higher achievable RC, too, if needed/wanted). Good stuff :thumbup:

Oh - and it's not a pain in the ass to sharpen, either!

My sentiments exactly,I have avoided a few knife purchases because they are using s30v,I already have quite a bit of the steel ,for me I would rather have ,for a change ,a more refined edge that cpm154 offers,while sacrificing working edge.
I definitely appreciate all the efforts that Spyderco puts out in our behalf ,thanks to Sal and his crew....

Why not offer a custom spyderco, through your website, like buck? You can select the steel, g10 color, etc...sure you would pay a premium, but it would satisfy a lot of customers.

That's pretty much been discussed and ruled out do to production time, space, and the extra personnel required.

I have used Buck's custom shop. They offer 420HC ( base steel for 110 folder and most knives), and S30V. They used to offer BG42 years ago but that's long gone. CPM 154 was offered in a Bass Pro edition ordered through them only. It's been deleted and no more are available. There is another upgrade from one company, Cabella's maybe? The Alaskan guide models in S30V. They cost as much as custom shop base models with non fancy handle materials like the Oak model I have.

The only other steels I've seen were some Sandvik steels ( 13C, etc.) offered in some newer model folders but not custom shop knives.

Thank you for the insight Sal. I think folks are excited about this steel, I know I am. As far as a model to roll the steel out on, anything from Golden would be, well...Golden. :)
I really think a Mlitary would make the best plastform, but I'm pretty well biased. If we can have it, we would love it. Waiting is a necessary part of life, and it would be worth it.
 
I would like to see a Military in CPM 154 also, would be well worth the wait. :)
 
Sal,
We have plenty of CPM-154 waiting to find a new home in Golden CO. Let me know what works for you.

Thanks,
Bob
 
I don't really understand this request. When something comes up using 154CM everyone bashes it and says they are going to pass on it because of the steel. In fact the OP just said he would pass on a Benchmade because of the use of 154CM. Now I know CPM154 is a little different as it uses a first generation particle metal process which improves the grain structure some. But how does this change the alloy of the steel? They are both iron alloyed with the same percentages of the same added elements. How does that change the alloy?

I'm ok with 154CM, though it is about as low as I like to go anymore. I bought one of the only production knives I know of that used CPM154 and it behaves just like 154CM. There are people who have praised CPM154 but since there are very few production knives that use it, I can only assume it was from a custom maker with a custom heat treat. In my experience a custom heat treat makes almost as much of a difference as the type of steel. A couple blades heat treated at a time perform significantly better than production blades where 100s of blades are in the furnace at once. I just doubt the average person, even knife knuts, are going to notice a difference between the 2 in a production knife, yet the ingot version gets poo-pooed all the time lately.

From what Sal said, it almost sounds like he was hinting that in testing S30V did better than CPM154. I guess it is one thing to try out a new steel. But most people don't usually want a steel that doesn't hold an edge as well. I would like to see Sal give us some testing numbers between S30V and CPM154. The fact they just changed the regular Manix 2 from 154CM to S30V says something. I know it's not the same, but it's not very different either. I just find it amusing to trash one steel and then request the same exact alloy that is made a little different.
