CPM S45VN is looking like it is going to be a winner! Looks like 63 HRC is easy to obtain and the sweet spot looks to be 64.

MCH, who is currently building with it?

I am not sure as far as a list would go. The one I know for sure is, is Triplebhandmade.

I would guess that at the very least these guys will if not already.

Shannon Steel Labs

Marauder Knife n Tool

So, I am guessing here but is S45VN just S35VN with an extra 1.0% Niobium?????

ie: a tweaked S30V

Who is making this steel????

CPM stand for Crucible Powder Metal so...?

Tim not sure where to start with this. I guess I could start with saying, with that mindset we would all be carrying Knives in ATS34 or even farther back 410, 420, 440!

Reality is that rarely is their a major jump in chemistry when advancing steels. But a lot of little advancements add up over time. I get that you are content with working with what you are set up for. There is nothing wrong with that.

I personally like to match up steels with geometry and heat treat that complement each other in the intended use. I would never make a hunting or filet knife in a steel like 3V or M4. Just not what those steels shine at. Both great steels. As I am not going to have a fighting knife made of Rex 121 or CPM S125V! Again not what those steels shine at.

I get that making knives with the newer super steels cost a boatload to make. I get that the majority of makers are unwilling to take on this task. It is not easy selling $700 plus plain Jane hunting knives. As I have said before I am very grateful for those that are willing and able to work with the newer super steels. As I am grateful for the steel companies willing to develop these steels.

Use what works for you! If you and your customers are happy with your product that is all that matters. Some of us are knife loonies and enjoy cuts above.

So asking that question puts me into some negative mind set???????

At first blush, I could not find CPM S45VN on Crucibles web site, hence the question.
I have now found that info and also watched the video you linked up for us.

Below is Crucuble's opening comment on that steel.

"DATA SHEETCRUCIBLECPM S45VN is a martensitic stainless steel designed to offer improved corrosion and wear resistance over CPM S35VN"

HMMMM

I will never use ATS34 (Hitachi) and left 440C a couple decades ago.

Although I appreciate the constant upgrade from technology, I do not have to have this weeks newest version of the .......
And I do appreciate those who constantly are designing, testing and tweaking the newest.........
Looking at the relevant differences puts things in perspective for me.

"It is not easy selling $700 plus plain Jane hunting knives."
----Correct, and I have no interest in that arena.

I want to make knives at a moderate price, of good quality and good R.O.I for the buyer/user.

Those who have to flirt with the leading edge-----I salute you and continue to hear about your findings.
Just don't get too carried away with the golden egg syndrome.

I think I will stop making posts other than what I am doing and let those who like that so respond.

I may from time to time ask a simple question though.

Keep the new info coming.

Tim not everything is about you! Nowhere in my post did I say what you were interested or not interested in. I posted a topic on a steel plain and simple! If you can't discuss topics in and around knives then maybe it is best you don't post. I know it isn't just me, as I remember when Rick was posting here a lot you were complaining to me about that. You are way too sensitive and insecure.

Well, I apologize to everybody here. I sure as heck do not remember ever saying anything about anyone too much to anyone

Heck I like and respect you and Rick both...and many others.

Not trying to imply anything is about me. I maintain a pretty low profile in life.
I have never been told I was too sensitive and insecure.
I was however trying to speak up on my experience/opinions
and ask questions to clarify others.

I enjoy this site and hope that I have never degraded it for anyone else and I have learned a few things here.

FWIW, I was impressed with the factory ZDP189 blade when properly sharpened as shown in that link above.
Guess it is all about the carbides.

Life is good.

Grind on and thanks for the interactions to all.

MCH, you need to learn how to play well with others. MRK asked a question and you responded that he's living in the past and using inappropriate steels in his knives. You always come on here with a superior attitude, which isn't needed.

What the [bleep] was that? Somebody off their meds?

Tim, can't wait to get my loveless pard!!....

Does every thread in every forum have to go down in flames just to feed someones ego? Used to be able to at least glean some useful info from the garbage but anymore it's like looking for a needle in a haystack. Nothing more than a place for folks to feed their insecurities.

I'm good until someone talks shiit to me jack!!!😂😂

Pardon my ignorance, how will this compare to M390?

If you have not taken the time to view the link provided by MCH, it is enlightening on sharpening and some steel comparisons.
The things I most grabbed on to where:
----There are some new steels that are very high end, ( CPM S45VN+++) but also some that have been around a while that hang in there. M4 got mentioned a couple times
as an also ran. I am liking that steel myself for now.
----How well the cheap Work Sharp actually performed when you get the "hang" of it.
----That a shallower edge angle and polished edge appears to hold an edge longer than a little steeper and 600 grit toothy finish
----How much the production blade (ZDP 189 steel if I remember correctly) of unknown Rc with a resharpening could go almost off the charts.

It will take a half hour or so but this is it from above.......

Also, thanks to Boise and MCH for patterns I used in the past that came from their input.

Cut on.

Oh I am sorry did you have anything to actually say about the steel in discussion? Or just crying because you have nothing of value to say? I could careless if you like me or not. I am not here to pad peoples feelings. But by all means show me where in my post I am wrong. I'll wait...........


Your reading comprehension isn't very good either! I never said anything about the steels he is using. I said and I will say it again really slow for you! With that mindset we would all still be carrying knives made from ATS34 and 410, 420, 440!

Again please show me where I am wrong in my post!

Back to the actual topic. I see production companies doing runs in it soon. Which is a great thing for the consumer.

I think M390 a better steel than S45VN. But the steel is too new to really know yet. But it also comes down to what you are looking to do with the knife.

Tim you're about as close of an internet friend that I have. I look forward to what you write and hope you continue to contribute. I found your question to be of interest and appreciate you sharing the Crucible page. I may have come across snarky with my CPM post but guessed you were looking for someone selling usable stock.


From your Crucible link:
"CPM S45VN is a martensitic stainless steel designed to offer
improved corrosion and wear resistance over CPM S35VN. Its
chemistry has been rebalanced so that it forms more chromium
carbides, while at the same time leaving more free chromium in the
matrix. The use of Niobium and Nitrogen in place of some of the
Vanadium and Carbon produces an excellent combination of edge
retention, wear resistance, corrosion resistance and toughness
properties making this the ideal choice for an EDC knife steel.

The CPM process produces very homogeneous, high quality steel
characterized by superior dimensional stability, grindability and
toughness compared to steels produced by conventional melting
practices."

But the Crucilble page also shares:
Edge Retention (CATRA Testing Relative to 440C)
Grade %
CPM S45VN 143*
CPM S35VN 140*
CPM S30V 145
154CM 120
440C 100

So CPMS30V has better Edge Retention than CPM S45VN - like any of us will be able to discern a 3% difference.

But the one item that would have me as a knife maker looking at this new steel is:

"In the annealed condition, CPM S45VN is much easier to
machine than CPM S90V and easier to machine than
CPM S30V. "

I suspect some here didn't actually read the Crucible Data Sheet.

Speaking of reading comprehension; yours sucks. You did say this, knowing that MRK just did a big run of M4 for hunting and B&T knives.
While not directly referencing him, you're saying that what he is using is wrong.

Jesus Christ you fuggers are like a bunch of old ladies! Nice try to put words in my mouth!

No what I said was I would not have a hunting or filet knife made out of a steel that is better suited for a fighting or camp/general purpose knife. What anyone else chooses to use is their choice. Personally I like to maximize the potential out of my knives. As I also said I wouldn't make a fighting or camp/general purpose knife out of Rex 121 or S125V! But you cut what I said to best support your effort to try to talk for me.

Again do you have anything of any value or do you have any knowledge to share with us on the original topic? I didn't think so. Have a great night.

deleted...remembering the grief I've taken here before...(even from folks I've helped with this stuff!)
