Also what is the name of your knife company?

that last test with the Delta 3V is truly impressive.

What an excellent example of the importance of heat treating as much as the steel type for specific designs and uses. Thanks for the data points! Have a great week.

Nate is the Bob Ross of the knife industry. Keep making those happy little carbides fellas!!!

One of your Delta 3V just went to the top of my wish list! Outstanding!

That CPM 3V is just... holy crap. 🤯🤯🤯🤯🤯🤯

Came over from BF. Great video! Thank you! Great to see some common blade steels compared to your heat treat.

That's a really fascinating comparison! The Delta 3V steel in particular is astonishingly resilient. However, my kitchen knives will certainly never be used to cut any bolts or chains. I look forward to eventually adding a magnacut blade to my arsenal.

Well, this is new to me. I love knives, metallurgy, and heat treating methods. I find it very fascinating. Awesome!

Love it. Nice to hear from you guys on here.

Excellent info, Nathan - another example of why CPK is a cut above. Thanks for sharing this.

so glad i found this video again!... been trying to find it for ages!

If I hadn’t seen that last test I wouldn’t have believed it.

Very impressive! Thanks for this analysis.

Would like to see a comparison of edge retention between your heat treat and the standard heat treats for magnacut. Also thanks for the video. I enjoyed watching it.

Extremely impressive fellas. Very good work.

Excellent video Nathan, very informative, can’t wait for my field knife in delta 3V to arrive! 😀

This is amazing and I didn't know how much I wanted to see this

Just goes to show what a great heat treat can do for a knife. There's so much focus on just the blade steel a knife might have but other attributes such as heat treat, edge angle, thickness behind the edge all matter just as much in the overall execution in creating a great knife.

Dude the inclusion of a richtig… amazing dude. Going down the generations. Apparently his knives range in the mid 50s for HRC

I can't wait to pick-up a few of your knives!

You should link your knives so people can go and buy some. Pretty impressive. Great video

I am sitting here awestruck! I mean completely flabbergasted! A knife cutting a nail and virtually unscathed afterwards floored me…but a chain…🤯🤯🤯!!! I just know, without searching, it will make me seem poor; so I won’t look. AMAZING!!!

Grumpy sends his love!!! Rocky is tagging along too!

incredible performance from those steels

i'll just leave a like and a comment to support your work and that you destroyed your own knives that you worked on and did an effort on them. I respect that you have balls to do this only to show us, thanks.

That green one cut the nail very nicely imo

Very impressive. Keep up the hard work.

That is downright impressive.

Nice video, enjoyed it. And yes, the chain cutting was awesome!🐒

I'm gonna look you up. Very nice knives. Thanks for the video.

Your Delta 3V is amazing!

I love my 440c and my D2 blade knives … perfect and not expensive… 😜✌️🔥🍀🍀🍀🌎🍀🍀🍀

Very informative, thank you!

Oh a few months back I found those radius plattens I got from you and decided to give them a try. It changed everything for me. Talk about a perfect grind for a chef's knife. I had some S35VN .140" stock. Never wanted to use it for chef's knives but now it do a flat distal taper out to the tip with a zero edges and pull the hollow up to the distal taper. Most of the contact surface is thinner than it would be on a FFG. That little bit of hollow might help with food release. The part I love is that I get the the very thin and slicy blade that is what I am doing with a chef knife but I get some weight and a very stiff blade that just feels better. I hope you keep making those things. I have only been using them for a few months and I am Freaking out about what happens when they wear out. If there is anything else you make for grinding I don't know where to find your stuff. It was really random when I saw them up the sellers page of BF.

...my kingdom for one of those delta 3v blades...love to show that off on my own channel! ❤

he gives off Bob Ross vibes except with knives

Your knives are awesome- I have a DEK 1 and UF which are fantastic and waiting on a Basic 5. My knife buying has about stopped except for yours and Joe Watson.

Dr. Larris Thomas, the inventor of Magnacut steel, said in an interview that the number one factor affecting knife performance is edge geometry. Understanding the intended use of a knife is important to apply an edge geometry that will optimize performance. Larrin said that a knife that might not seem very good can be made better by modifying the edge geometry.

Keep up the great work.

I've never, EVER seen a knife cut thru "chain" that thick, or any chain!!! I, am impressed!!!

Right on man. Best wishes with the Magnacut. Hopefully here soon I'll own 2 knives from you - the other being a 3V model.

Awesome thanks for the video!

I'd love to see a comparison of d3v to 15v both above 63 hrc.

Holy smokes! Cutting the chain with such little damage is remarkable!!!!

I dream of owning one of these fine blades Sir.

So, a little longer soak time for the Magnacut. Thank you for that tidbit. Are you using LN or dry ice? I imagine with lower austenitization temps. the dry ice is sufficient because retained austenite doesn't seem to be as big of an issue with this steel.

Let's get that CPK FK2 in Magnacut cranked out! Yeah, buddy!

I've always wondered what an optimized HT of yours would result in if you ever tuned one for 1V or S7. I'd definitely buy anything you made! Hell, I already do! Your D3V is downright incredible.

The modern super steels are great for edge retention, but are they tough as carbon st with a good HT? I know people are overly focused on edge retention.

I don't really care about stainlessness. I've used carbon steel kitchen knives for over forty years now. They don't rust and I can get a fantastic edge on them. If I could get a better edge on stainless, I've never found stainless gave me any better edge retention, the patina isn't a problem -- they 'grey' rather than rust here in the damp (but not humid) UK and the edge is both fantastic and easy to sharpen.

Hello! I’m a big fan of your work and was wondering if you can do a demonstration with cutting bone? Thank you!

I have Carothers knives in D3V and aebl and they nail the HT on both of these steels. One of the best fixed blades around.

There's a video on KZfaq of a Buck 119 in 420 HC chopping through a nail with minimal damage too. Buck just does excellent heat treating.

Just got a DEK 1 from the preorder and am loving it. Looks great alongside the UF2 👍🏽. What is the knife that went before the Busse?

Exciting news indeed!

What make/model is the Green chopper?

Really impressive results. What about S35VN?

Great video - research

How thick do you need to run those to do a nail? I might not have it perfect but when I tried with my 3V blades and I got damage. I usually do kitchen knives and like thin edges. I am making some bigger knives and I am leaving the edge .015"

Great video, it was hard to head you though.

I love technical videos.

Wish you would have tried the original magna on the bolt like the other two treated?

I use bolt cutters on chain but everyone is different.

Impressive. I saw someone do this with the Ontario TAK1 (older 1095 stamped version) and no damage to steel. So I got one.

Legend has it this man cuts his steaks with an angle grinder.

Nice video !

Just curious how aeb-l steel stacks up toughness wise. I have it on a few balisongs and it is insanely tough and stainless. It's not on the same level as 3V in edge retention, but I'm dying to see it against 3V in toughness.

what metal of these offers highest edge retention while maintaining a sturdy toughness for bushcrafting?

Questions: 1) How does regular CPM-3V compare to high carbon stainless steels, as opposed to this Delta optimized CPM-3V?

you deserve a nobel prize

What is the rust performance and how easy is it to sharpen that last Delta 3V knife.

What is the best blade material for a camping knife?

Some guy on Blade Forums was trying to say that the Delta Heat Treat was just a marketing scam. Personally, I think he's talking out of his ring piece, but it is what it is. Any blade that can slice through a chain that thick without taking a chip or major damage is a big win! Great job Carothers!

11:42 Amazing test starts here.

I would love to see other tools use Magnacut, like screwdrivers, wrench jaws, sawsall blades, and other high demand tools that might get wet

Damn, that 3V is impressive!

Came here for the Magnacut info but got more intrigued by your MIDO watch, had to google it, is it a Ocean Star? What model? Looks the part!

Many indestructible knives are too thick to cut well. Will a steel upgrade led to a thin knife that won't break?

Incredible!

what was the hardness on the two magnacut samples you had?

Good time to be getting into knives I guess!

we need to talk. AMAZING

I super wish you made folders. I live in California and fixed blade carry here is annoying. I'd instantly buy a folder from you.

Which steel do you like for the knife?

I subscribed to youre channel. I was interested in youre open analysis you seem to be curiouse. I like that 😊 I dont know whats youre location but where I live the winter temperatures can drop down to - 20'C to - 36'C Celsius and if youre out in the forest and have to make firewood its nice to have a Leuku hanging on my belt that can replace the axe if the axe is lost in the snow. I chopped wood with a Marttiini Leuku that has Marttiinis usual chromium stainless steel and I chopped a lot wood for about a year with it everytime we made a camp. It didnt break thou had some small chips. I was wondering does anyone know how that Magmacut performs in - 20 to 36' Celsius in a long period of time?

Holy crap that delta 3v is ridiculous. I need

Mind blown for sure

Are you willing to share your recipe? I normally use Nitro-V but want to try Magnacut!

Man I don't know exactly what he did but I recently bought a Medford Bonfire in 3v and this thing has a massively thick 7.5mm bladestock although I could have done without the hollow grind but it came with a relatively thick behind the edge bevel so I laid it back a bit and slightly convexed it by hand on diamond plates and wow it became a decent chopper and feathersticker while still being able to cut a 16penny nail then cleanly slice paper that was the first time I'd gotten a knife to do that and take almost no damage at all while still being a good performer I mean anybody can put a nail chop edge on a blade but can it also perform well in other tasks after chopping the nail?

Delta 3V is pretty much untouchable. Insanely tough and fairly stain resistant. Magnacut looks impressive for a fully stainless steel for sure, but can't see it being better option than the Delta 3V for overall usage.

Delta 3V is beastly!

Amazing

Curious what all the edge thicknesses were

Great video Nathan. It would be nice if you can throw in AEBL next time heat treated to the same hardness to MC. It would be interesting to see how they compare once they both pass 62.

All I do in the out doors no need for a Super (hard to sharpen) Steel. Probably is a great steel but can you sharpen it on a sand stone in the field?

watching intently!

Are you guys out of Wisconsin?

Hey man where can I buy that super field knife?

Wow you're amazing sir
