Hey guys, this is my attempt to crunch the metallurgy miracle that is CPM MagnaCut Steel into 24 minutes of understandable conversation. This is a formidable task, but I am so pumped that Larrin Thomas has created this blade steel, I'm going to give it my darndest.
Check out these articles:
knifesteelnerds.com/2021/03/2...
knifesteelnerds.com/2021/10/1...
Cheat codes: How did he create one of the most effective high carbon stainless knife steel by DROPPING both carbon and chromium in Magna Cut?!
Alloy breakdown: What is the nitrogen and niobium doing to boost the characteristics of MagnaCut? Why is Chrome it's own worst enemy in knife/cutlery steel ordinarily?
Composition in contrast: What ACTUALLY makes CPM Magna Cut Steel different from every other knife in your collection, and why do I think you should buy a MagnaCut knife when you get the chance?
CPM MagnaCut Steel - truly; cutlery, knives, and stainless steel may never be the same!
Also check out my tutorials on dual grit sharpening.
What's a dual grit edge, you may ask?

It’s a great starter video, if you want more technical details, Justin at Engineer’s perspective made a great video: kzfaq.info/get/bejne/hL12i7t0st7LqIE.html And Larrin Thomas, the developer also made a pretty comprehensive explanation: kzfaq.info/get/bejne/ms1kpMaVqcjFaas.html Cheers!

I read the article by Larrin and I really appreciate your comparisons and your simplification. Dr. Thomas is a metallurgist working in the automobile industry as such and he comes from a family of knife makers. I doubt that there’s more than half a dozen of people in the world that have the knowledge of steel and the passion for knives to be able to do what he did and there’s even less than that that are willing to take the financial risk. Luckily for us, it takes only one Larrin Thomas.

I grew up not poor, but with a healthy appreciation for the value of a dollar. I've owned dozens of gas station knives (just the regular ones not the idiotic looking ones that are as likely to cut you as what you're wanting to cut) but after hearing about Magnacut I bought a Pro-Tech Mordax after months of searching and while it necessarily wasn't life changing for my day to day, I treasure that knife and carry it with pride because I mildly know what went into its creation and I may have started an addiction. I really like your break down of the steel and you definitely earned me as a sub.

@voltsoftruthBSbuster Жыл бұрын

I think toughness is more the ability of the steel to withstand sudden shock, impact. Where as the metals ability to withstand "load", as you put it measures its strength. For example you can place a bar of steel in a vice, and start hanging heavy plates on. The amout of weight it would take before the steel snaps, or permanently bends, "takes a set", would measure its strength. While placing the same exact piece into a vice, and suddenly striking it with a 5lb sledge hammer to see, if it flexes and returns to true, deforms, and has dents and deformation spots where the hamer struck it, or just shatters to pieces would gage the steels toughness. I just bring it up because often people use the term strength and toughness interchangeably as if its a same quality. When in reality those are two different qualities of the steel. A steel can be very strong, meaning would take a lot of weight/load before it breaks, but not be very tough and snap suddenly when subjected to a violent blow. And same can be true in reverse. A steel can be very tough being able to take massive blows and impacts with out breaking but put in a vice and having heavy loads hung from it, would start to flex, bend and ultimately break much earlier under less load than a stronger steel. The trick is to find a balance where a steel is both strong and tough at the same time. And its typically not a easy task, since strength often increases with higher hardness, but toughness decreases with the same high hardness. And the reverse can be true too, toughness increases with lower hardness but strength decreases with lower hardness. And every steel has a different "sweet spot", depending on its composition. Some lower carbon steels can be tougher and stronger at harnesses of 60+rc than steels that have higher carbon content and their optimal sweet spot might be below 60rc. No two steels are the same and altering even the slightest chemical composition can have unexpected changes that can be at times beneficial or detrimental. This is what makes the science of knife steels so frustrating and exciting at the same time.

@homeslicesharpening Жыл бұрын

Interesting thoughts! Yeah, I get what you are saying. I have never seen “strength” as you describe it being measured in a quantitative way. Only Charpy testing for toughness, and Rockwell testing for hardness. As such, I find that for most knife users, it’s easier to discuss the balance between hardness and toughness using numbers as it makes it more easily accessible to a wider audience. Hardness is not strength as you describe, but combines with composition and structure to create strength, or lack thereof. But I’m trying to create a place for people who don’t understand to start their journey. Not disagreeing, just simplifying - hopefully that makes sense. Thanks for the detailed comment!

@@tacticalcenter8658 3v isn't stainless. s30v is. s30v is an excellent well balanced cutlery steel. It's not as stainless or tough as magnacut tho. Magnacut is a newer one that's closer to a stainless version of 4v. It's basically s40v. Sorta. Compared to 3v Magnacut isn't nearly as tough as but it has marginally better edge retention. If you're not worried about corrosion, obviously you could do way better in terms of other performance metrics. Magnacut is all about being extremely stainless with high toughness and good edge retention. But compared to less stainless steels, it's going to have less edge retention and toughness. It's always a tradeoff. Even if you are worried about corrosion, a laminated blade, san mai style, should always be considered an option. I'd like to see someone try something like 10v or 15v laminated with something like lc200n or some other very stainless, very tough steels. 14c, 420hc, even aeb-l, for a pocket knife, laminated 3v or 4v might be interesting in a kitchen knife.

Like the vid overall but I have one little question. In the beginning you say toughness leads to edge stability but I always thought that it was hardness that prevented rolling.Did I misunderstand?

@homeslicesharpening 2 жыл бұрын

That’s an absolutely great question. There are a couple of main factors that contribute to edge stability, so far as I understand! It seems like the main ones are hardness, toughness, and grain structure/type and size of carbides. Hardness tends to make the edge not want to bend or deform or be worn away (but can lead to chipping) - toughness contributes to age stability by reducing the likelihood of chipping or fracturing, or said another way toughness increases the ability of the edge to flex or bend without breaking. Grain structure dictates how large individual Crystaline sections of the steel are, and carbides play into that and are each their own hardness level and size. Together these 2 play into the toughness of the steel AND dictate how large chips or damaged portions of edge will be. When I say that toughness is needed for edge stability, I mainly mean that A) toughness reduces the likelihood of the edge giving out by chipping and B) steels that have a higher level of toughness can afford to be brought to higher hardness (also increasing edge stability) without the worry that they will become too brittle. Does that make sense? It was clear in my brain but I feel like it came out a little garbled.

There are steels with no chrome, I think all of your 1095, 1075, 1055 steels are like that! But steel is a wild animal, man - it rarely does what you think it should. For instance, they have found that up to a certain threshold, steel's hardness and toughness capacity actually improves with a bit of chrome. This is why you see KaBar using 1095 CroVan or many makers using 80CrV2. In both cases the carbon steel has trace amounts of chrome added, because somehow it makes the atomic structure cleaner and increases the toughness of the steel. Anyway it's a delicate balance, 0 chrome is less tough, tons of chrome is less tough, but there is no perfect amount. Which is to say, the perfect amount depends on the purpose you want to use it for, and how much carbon you put in that it is bonding with. Hopefully that makes sense - thanks for the comment!!! PS Blueing would be interesting though. I understand it does harden the outer layer of the steel somewhat.

At 2:25 you say Larrin, I presume the name of an individual, as if everyone watching this video is already supposed to know who or what a Larrin in. If that was indeed the case, just wondering, what would be the purpose of the video? If everyone already knew exactly who or what you meant when you said that, why would they need to watch this video in the first place? Does that make sense? Kinda seems like the video is more about explaining something you're trying to learn about yourself so that you can absord and understand it better, rather than really a video designed to educate an audience from a place of expertise. It's cool. Just a bit odd.

Hey Jeff - welcome to the channel. I am sorry for the lack of context. I had assumed at the time that most of the people looking into MagnaCut steel were doing so because of the article written by its creator, Dr. Larrin Thomas - who runs the excellent website knifesteelnerds.com Since that time the steel has exploded in popularity, and many folks know and own it without understanding its origins. My video also has grown in popularity slightly, as the steel becomes better known, and my oversight in not giving context in the video is more glaring. If I could go back and edit it, I would, but KZfaq allows no such thing. If I make further videos about MagnaCut I will take your advice into account. Thanks. If you want to know more about how/why Larrin Thomas developed MagnaCut, his article is here: knifesteelnerds.com/2021/03/25/cpm-magnacut/ My apologies that your comment was barred from the video initially. I found that KZfaq had sorted into the spam comments, and I rescued it from there and published it. Cheers.
