80CRV2(1.2235) spank them all in this edge durability test...

I know this is not any scientific and more of an another steel marketing but in the description(google translated from German tho) that they HT those PM steel to data spec combine with subzero...

What do you think about this?

 
It looks like the knife made of 1.2355 (80CrV2) was a commercial product while the rest were made by them. https://www.schmiedeglut.de/bushcraft-knife-sacki-survival

It also looks like they found Vanadis 8 to be tougher than Vanadis 4 Extra which is of course odd. Do they ever specify hardness and edge geometry in the video? I can’t stand trying to sift through these videos for the pertinent information. At least this one isn’t as long as many of the other “testing” videos.
 
So the low carbide differential heat treated steel proved to be more shock resistant than the high carbide steels?

I don't think we need the video for that one. Yes. Vanadis 8 and Vanax would make a bad axe and an expensive one.


In the video we don't get any information on HT, geometry or sharpening.


Seems like he just want to show why he likes his 80crv2. He didn't do the tip test with his baby :D

They use Uddeholm HT protocol , if you look carefully where he show all blade with broken tip you can see that all test blade have same shape and grind geometry...

Nice you found the information?

What was the Behind the edge thickness? What edge angle? How were they sharpened? power equipment? Water cooled? Hand powered? What abrasive was uses to sharpen? What was the bonding on the abrasive? What was the grit finish? What was the initial sharpeness?

How where they HT'd? Sent out to HT? Did he HT?

Vacuum? Salt? Electric furnace? Atmosphere protection? Foil, coating? Inert gas?

Was a cryo used? Snap temper before cryo? Time to cryo after quench?

How were they tempered? Any control on the tempering?

Are we testing steel or his processing?

Without more information it's just entertainment.

Larrin, I think 1.2355 is S7, not 80crv2.
 
Regarding the OP, it’s obvious that 80crv2 will be tougher than high alloyed steels like Vanadis 4 extra and specially Vanadis 8, although well made Vanadis 4 extra can take severe punishment, with the right geometry, of course (I have more than one Vanadis 4 extra knife and never chipped (one very thin lost the tip (1 mm), but I was prying wood with it) none of them, even a chopper).
 
I expected the V4E to be roughly comparable to 80CrV2 based on our 1084 results. The others are a significant step down.

You’re probably right, Larrin. But I would put it more near cpm3v than near V4e, let’s see. Nothing that can dethrone 8670!

I’m really curious regarding A8mod results. The A8mod that we use here in Europe is around 8-9% in Chromium content, but A8mod from AKS is much lower. I’m sure it is impossible to predict what’s the toughest version, but do you think 8-9% Chromium will increase A8mod toughness? Or the less Chromium version is tougher? I just ask this because in Bluntcut tests A8mod from AKS (with standard heat treatment) chipped badly cutting nails and this is not the behavior one should expect from this steel. Maybe geometry problems?
 
I never realized the AKS A8 mod has 5% Cr. Looks more like A8 than it does chipper knife steel. I wouldn’t think that increasing Cr beyond 5% would improve toughness.
 
We still need more V4E and 4v conditions too. I think there are a couple of those still out there.

Yes, and M4. I also found a 2” wide piece of 20cv, just enough to make transverse samples. I’ll have to check what’s out there still. Probably 30 or 40 conditions.

Comments like this are how I learn how much I don't know, lol...

And yes, in light of all this, it's just entertainment.
