CPM Prototype Steel
Re: CPM Prototype Steel
I can confirm that iron is the primary element of the prototype steel.

Gotcha.
Thanks for the clarification.
Pretty work.

Re: CPM Prototype Steel
I wish I could contribute something here. That knife looks awesome.
Re: CPM Prototype Steel
So what is the intention with this steel? Toughness, corrosion resistance, edge holding or is this an another attempt at a being all things for everyone steel? Seems we already have seen an attempt at all things for everyone? I will be interested to see how this one is marketed and even more interested to see if it can live up to the interweb hype machine.

I think it's fun to see results without knowing the intended purpose, because it's easy to develop expectations once you know what the intentions are.
I'm betting it's a flavor of MagnaCut that has higher edge retention at the cost of corrosion resistance and/or toughness.

I'm neither a steel nerd, nor do I have very good memory. But as far as I remember, Larrin's intention with MC was to create a more balanced steel than what was currently available. It wasn't intended to be all things for everyone, just a little more of everything for those who didn't want to give up too much in either one category to get enough in another.
To my understanding that worked out quite nicely, and even better than expected in the stainlessness category, but (and now I'm really going off my poor memory here) I seem to remember Larrin was quite quick to remark that he wasn't finished. And given the opportunity he saw potential to build on his experience with MC to create more specialized versions that would be more geared to excel in specific areas.

Well, this is interesting. I'm late to the party because of the day/time difference. I can't wait to see how this turns out.
BTW, Shawn, I like that knife design a lot.

Re: CPM Prototype Steel
Hi Larrin,
I would like to say that I, for one, really appreciate the time and effort that you extended in your life path to get to where you are. You are an asset to our industry.
Thanx to your father and I'm sure that your Mother also deserves a vote of thanx as well. Keep up thew good work.

Re: CPM Prototype Steel
Yes I was…. I am a big fan of Dr.Larrin, I have and have read his books. I have a MagnaCut blade and it didn’t seem to be an improvement, in my use, over S110V. If I’m going to pay extra for a steel I might as well spend what it takes to get the steel that works best, in my use. Sorry if that’s an issue for you. Like I said I’m looking forward to see what the new wonder steel can do for me.aicolainen wrote: ↑Wed Nov 06, 2024 7:40 amAre you referring to magnacut?Jesla wrote: ↑Wed Nov 06, 2024 5:07 amSo what is the intention with this steel?

Re: CPM Prototype Steel
Dr Larin said he would make a couple variations of Magna Cut so this could either be the more wear resistant one or the tougher one. My bet is the more wear resistant one. My vote is to name it “Magic Cut” or “Mage Cut” and the tougher one “Chuck Cut”

Oh for sure. People already hate this steel because they hate anything that gets hyped.
We may as well start a new thread "We don't need to CPM Prototype Steel them all" because we're well on our way to a zillion requests for this steel that we don't even know the name of yet.

Re: CPM Prototype Steel
But MagnaCut was never advertised as being an upgrade for every steel in every parameter. From the very start it's main selling point was balance, not giving up too much of any of the trifecta characteristics (edge retention, toughness and corrosion resistance).Jesla wrote: ↑Wed Nov 06, 2024 12:45 pmYes I was….

If You compare it to an extreme steel like S110V and are mostly focused on edge retention then of course it won't be better. That's because S110V is an edge retention (and corrosion resistance to boot) monster

That's because S110V is an edge retention (and corrosion resistance to boot) monster. But it has a couple TIMES lower toughness at similar hardness so it might not be the best choice for a do-it-all blade compared to MC
In my own use I heavily rely on stainlessness, so Spyderco and the Salt-series was a godsend to me. But up until magnacut, I had to choose between rather low edge retention with extreme corrosion resistance (H1/H2/LC) or extreme edge retention in a brittle steel and non-salt construction (S110V).
Though often tempted, I never acquired a S110V knife, as it always felt like a Salt was the better trade off, even if I had to give up quite a lot in edge retention. With Magnacut joining the Salt lineup I don't have to do trade offs to a degree that affects my usage.
I'm very impressed by what Larrin did here. Not only did he achieve his goal of making a balanced steel that performs above average in areas of the characteristics trifecta, but I think he also lifted the idea of a balanced steel from boring to cool. It was quite the gamble. As if succeeding with a new steel recipe and convincing a foundry it's worth pursuing isn't hard enough, consumers that have been spoiled with super steels out-doing each other for years now have to be convinced that balanced is now the new super power.
Doesn't sound very exciting, does it? And I for one, wasn't immediately convinced. But he did it. The test batch performed according to his estimates, and the idea of balanced caught on.
Maybe it even caught on too much? There's definitively an argument to be made there, but the superstardom phase of MC will eventually pass and it will find its niche. We all agree there's no need to magnacut them all, but when the dust settles we'll be better off for having it.
Re: CPM Prototype Steel
First, I never said S110V was all things to all people. I said IN MY USE I have found nothing that out preforms it, IN MY USE. Let’s see you said BALANCED, balance in this case, I believe refers to compromise. When you use a 1 to 10 scale and you have a cluster of steels hovering above 9 then I question the validity of the scale or tester conclusion.horzuff wrote: ↑Thu Nov 07, 2024 1:40 amBut MagnaCut was never advertised as being an upgrade for every steel in every parameter.

This new steel may very well surpass S110V IN MY USE, we will see. I am waiting, with everyone else to see if the steel equals the hype, IN MY USE.
Why do you guys jump on and try to shut down anyone in this forum that doesn’t toe your line regarding YOUR PREFERED steel or method of opening and closing or (insert your choice here)? MAGNACUT and for that matter any steel has to prove itself to ME. I DON’T OFF HAND ACCEPT INTERNET HYPE OR SO CALLED “TRUTHS“. If that is a problem for you, you have a personal issue to workout.
