Nate does Magnacut

It has a high enough corrosion resistance that Spyderco is using it in their Salt line.

I have no doubt that Magnacut's corrosion resistance is excellent. I guess what I was trying to say is that corrosion has never been a problem for me with D3V. And I use it in the kitchen quite a bit, where it definitely gets wet and messy. I'm pretty fastidiuous about cleaning and drying my knives right after use, though. However, I don't have occasion to use my knives in a salt water environment. I guess if I did maybe I would ditch D3V for Magnacut.
 
Pretty cool but at this point my trust in D3V is unwavering.
Skinned quartered and cut up a whole mule deer without sharpening no issues. Including popping the leg joints and neck; lots of contact with the spine and ribs along the way doing backstraps.

I touched it up after on a DiaFold stone more because I felt I should than actually needed to - was still deadly sharp after the whole thing

-this was with a FK2*

Always appreciate a Nathan video and explanations, testing, etc.


Nathan the Machinist Nathan the Machinist The DEK 3 has a higher HRC spec for the D3V than standard. Do you have a target HRC for Magnacut on the DEK3 and is it different than what you’re targeting for other models?

Thanks!

Not Nathan the Machinist Nathan the Machinist

but in the video, the blades with standard heat treat had the number "62" written on their back and he said one of the new heat treat would be hard and one of them will be soft. So, I will not surprise if I see 63 on DEK3 and 60.5-61 on larger knives.

I don’t see magnucut as an upgrade on fixed blades. I think Delta 3V is still at the top of the food chain. Magnucut in a folder is probably excellent though.

top of the food chain for breaking through doors and smashing concrete? Yes, sure it is (well actually not ;) but anyway...

in my opinion, a steel that is best suited to 60-61 HRC and therefore requiring a thick behind the edge thickness and relatively obtuse secondary bevel so it will not roll can not be the top of the food chain. It is an excellent knife steel for sure. For a user who knows how to use a knife, it is stainless enough, tough enough (actually more than enough) and has wear resistance enough. It is a hard use knife steel that is suitable for a reasonable knife geometry and I like it but I know what I am buying and it is not the king. Once you used a thin knife with really hard steel there is no going back. And that's why there are steels like 4V and AEBL. Even CruWear could beat 3V once the knife is thin and hard enough.

I bet Magnacut would make an awesome set of kitchen knives….I would for sure pay a pretty penny for a CPK 10” Chef’s, Santoku, and Petty knife in MC with a nice block to keep them in.

If I remember right, Mark4444 Mark4444 mentioned Meglio Knives.

Almost ordered one.

Live link removed as this is not a BF supporting entity...but they are sold by site supporting dealers.

I’ve had plenty of knives in 4V, Cruwear and a few in AEB-L

Id still choose Delta 3V over any of them if possible. Guess I need to learn fine art of cutting things before graduating to 3/32 stock and 64 HRC. 4V does take a wonderful edge, as does Cruwear

I am never one to jump on a new steel just because it is new, but if CPK is spending time and money researching Magnacut, then it makes sense to me that it must be a phenomenal steel for some settings. It does not need to be better than D3v for a badass rugged knife in order to be useful. Do you run the same tires or tire pressure for all conditions? 😀

👍. Would Absolutely not would I run the same tire pressure year round. I wouldn’t use most stainless steels to chop, I wouldn’t use tapatio on grape nuts. Magnucut has my attention in folders, small fixed blades… I think the UF, FK2 and HDFK are perfect as is.

I didn't see it mentioned in the video, but was the D3V blade also 18 DPS like the rest of the blades?
Click to expand...

No, it wasn't. It was 20. Our standard angle is 20 for that pattern and I pulled it from a stack. Not a valid scientific test, but I didn't want to end the video on a down note and it was an impromptu cut. I was demonstrating Magna cut against some carbon steels and broke it on some bolts and I wanted to end the video on a good cut.

And then, there was a little brouhaha about cutting a chain a while back. That chain was included in a lot of grinders that I bought at an auction with an unknown background that was clean and not rusty and people, both on blade forums and Instagram, accused me of cutting aluminum or lead. So I wanted to show a rusty chain cut. I've had it sitting out in the rain for a while.

It was not a perfect demonstration but I did not enter it with the intent of misleading anyone, but these knives are normally 20 DPS. I reduced the angle to 18 for development work because it makes issues with edge stability more obvious. Delta 3V can cut a bolt or a chain at 18 DPS without blowing out. There will be a little more edge damage but it is not some kind of a threshold where things start just blowing out because the angle is a couple degrees narrower.

A flaw in the demonstration due to poor planning, not some nefarious intent.
