MagnaCut Knife Steel: The Complete Guide 

Great little video. For me, the steel is important, but shape is just as important. Has to do the job and feel good in the hand. great knives.

THANK YOU for the comparison to 52100 on toughness! Always like that steel and the comparison is helpful!

Looking at Larrin's toughness chart, people can crap on 420HC all they want because it's not the new "super" flavor of the year, but I am impressed. This makes sense because the destruction tests on the Buck Nighthawk or 119 is about as impressive as it gets. I was interested in that new Ontario SPL Pack Knife in Magnacut, but at this point I will never get rid of my Buck 650 and 655 Nighthawk's. Stupid of Buck to discontinue them and really stupid of our incompetent military not to issue them as their primary knife back in the day. In addition, 420HC is easy to sharpen in the field and tough and they are also excellent dive knives. But Buck also knows how to heat treat their production blades. Glad I found you all, Ill have to check out your blades. Cheers from Idaho!

Thanks for the vid! Elmax is the only PM stainless I like, but I’m looking forward to trying this!

As an avid Fly-fisherman, I like stainless steel. Although my other knives are mostly 1095 I have not found a stainless that is as tough. I am really hoping that you will come out with the Mini-Speedgoat in magnacut steel. I think that would be my perfect fly-fishing knife.

Corrosion is not about the blade. That is just patina. And this is commonly prevented by silly coatings. But it is the edge that corrodes first because it is thin, exposed and not protected.

AEB-L is a very tough stainless steel that has good edge retention and is easy to resharpen and takes a wicked edge because of the fine micro grain structure. I love MagnaCut but it’s expensive. I would love to see MKC produce some of their knives in AEB-L as a lower cost alternative.

I just bought one of these knives. I'm looking forward to giving it a whirl. One thing, in the last video he said the guy had a masters, in this video he mentioned a PhD.

Calling these grades "knife steel" does detach you from some of the usual tool and die industry standards. We had to learn that the hard way. I'm glad others are having success with Magnacut. Our stress relieving peening process has exposed a LOT of defects within the material we've had a chance to work with. We have several videos on this but If you're interested, here are some visual examples and more information: Magnacut Voids & Quality Criticisms ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZL0B4Y-_pK8.html

Can’t wait to get my triumph xl here in a few hours hopefully I get it before they sell out

👉 Great video, but I have to correct you on one issue. There are elemental metals that produce micro-thin oxide layers that actually serve as a layer of protection from further oxidation/corrosion(ie. chromium, nickel, tin, zinc, aluminum). But iron is _not_ one of them. When the iron in steel oxidizes(rusts), it does _not_ form a protective layer. Iron oxide(rust) is flaky, and it eventually separates from the clean iron underneath, allowing oxygen & moisture to penetrate and further oxidize the iron within. Its why you find old, non-stainless iron or steel items left in fields or ditches(or wherever), which have rusted right through to their cores. Its the addition of 12+ % of chromium to iron/steel that gives it "stainlessness". Its because when chromium oxidizes, it's oxide layer isn't flaky, and it does form a protective barrier preventing further oxidation. When you add enough chromium to an iron/steel tool, the 12+% of chromium within will impart its protective oxide layer to that steel. I only know this because I bought an element collection almost 20 years ago, which was put in a non-climate controlled storage unit for over 10 years. But the chunks of pure chromium, tin, zinc, nickel, niobium, etc are still just as shiny as the day they left their refineries, whereas my iron sample looks increasingly "dingier".

Just ordered a BR fin and bone in Magna Cut. This will be mostly for use in the kitchen as I did not have a dedicated boning knife. I have not had much trouble with tool steels as far as rust goes and I think I could have done with A2 if it came in that.

Great video but I don’t think 52100 is tougher than MC. It’s on par with 4V, which is much tougher than 52100. I use both in knifemaking but have not tested MC to failure personally. Just going off Larrin’s data. Have you found a different result from actual testing at the same hardness, around 62 or 63 HRC?

Hoping that 62 - 63 is the ball park for Rockwell on the Speed Goat I ordered. When M390 was the "Hot steel of the day" 59 HRC killed it for me. Generally speaking chipping has not been an issue with blades I carry. Great Video... your explanation of patina was outstanding.

Will you ever be carried by Blade HQ?

i go to huge deer camps. 40 or 50 of us. none have new steels

Well, the next hyped Wunderstahl 😂 I have in ears how ZDP189 was hyped back then. As you know the propertys of steel depends highly on the quality of the heat treating process. And that is what it is all about. The more complex the steel is going to be the more fails you get after heat treating. And when you rely on your supplier the brought in condition varies at the very beginning as well as the ginding process changes the samples. So, at the end, there will be lots of blades announced as MagnaCut mega blades that fail or don't have any advantage to other steels but a stamp on it to be better harder tougher stronger. It is a good steel but onky if the knife maker knows what came in the shop, what the manufacturing process did and has a good heat treatment done. Marketing is a big weapon. No offence. Just what I learned.

PLEASE show the KNIVES .... !

Stainless steel just isn't tough. AEBL man that stuff is so not tough. what junk. Very insightful. Wait, whats that? AEBL is actually extremely tough? It's a lot tougher than say magnacut until you get into 63+ hrc, which I doubt is relevant to the knives you sell. What really makes magnacut special is that the steel stays tough at high hardness, that's one key thing of many things that makes it such an excellent knife steel.

wrinkler knives are the best!

MC has "a little more" wear resistence than 52100? lol what? MC is like 2 or 3 categories above any low alloy steel. 52100 doesn't even anywhere near the abrasion resistence of any basic stainless steel, like say AEBL... which itself is lower than cutlery stainless steels like more and bigger carbides like say VG10 or better yet 154cm. MC is a full category above those steels like 154cm. It's not "a little more." it's a whole shit load more. Like, damn I can't even use a regular whetstone to grind this stuff kinda more. It's a vanadium stainless steel. 3% vanadium and a little niobium to boot. 52100 will lose bite after like a dozen cuts into mild materials. MC will do idk, maybe 10x better in the real world in that regard. It's a massive difference. But it's also a massive difference when it comes to sharpening as well. 52100 will take a scary edge with very minimal effort. Grinds like butter on standard traditional abrasives. MC won't even achieve it's full potential edge keenness without using superabrasives.

I'm have no intention of bombing steel types. Certainly many great steels out there. From fish to large game, farm use, being in bush weeks at a time and kayaking. I haven't found anything my 1095 isn't capable of. I need a steel that is field friendly not a Super (hard to sharpen) Steel needing jigs and mechanical equipment.

Magna-Cut is tougher then 52100.

If you're a hunter, or any kind of outdoor nerd and you're using an outdoor, camp type knife hard enough that you break the steel, if there was no defect in the steel, you did something so incredibly stupid that you shouldn't be allowed to go outside anymore, or you're an idiot "survivalist" youtuber who just went out to intentionally break something for some sort of self gratification or attention seeking reason.

I thought Magnacut isn’t a stainless steel because it’s less than 12% chromium. Tho it has some characteristics like stainless, it’s not stainless. Atleast that’s what I learned.

Sounds like just another sales gimmick. I thought s35vn was made for knives because everyone wanted easier to sharpen. Before that 154 was a stainless for knives. I personally like 14c28n mostly because it's not expensive. Hard to charge $200+ for 14c28n.
