Just read some comments about me.
Man that group is pretty ............................well I do not have anything nice to say, so I will say nothing.

My AK, TGLB, NMFBM and many others have done pretty well over the years

Cool! By the way, David made excellent sheaths for all three knives! Thank you!
 
This renowned forum is a true school.
I've learned a lot here and every day, I learn more.

I'm taking advantage of this topic to post a video of mine, where I did a forced test on two knives, a Morakniv Robust and a Bahco 2449. Two excellent knives.
My intention was not to destroy them, as I never made a video with that objective, but rather to test them to the extreme.
Because some channels I follow on YouTube posted this knife as "indestructible".
So I carried out the extreme tests to show that to call a knife indestructible, it must go through really severe tests.

I expect from noble gentlemen a realistic opinion, with criticisms and opinions. I certainly won't be offended.

Thanks.

Below is the video:

 
Regarding Joe sabotaging the blades, he got the coated model so I don't see how one could heat and quench that without ruining the coating. I don't imagine he has an easy way to put the coating back on to cover up such nefarious acts so I'm less inclined to think he did something like that.

I think the knife would have failed earlier on the car or the bend test if that was the case. The blade seemed to do fine until it underwent shock on the concrete block.

Never heard of a Bahco. I have tons of moras though. Simple formula, low Rc, low carbon stainless steel with a scandi grind that is flat sided steel to the edge makes for a very tough little knife. They don't hold an edge long, but it's easy to put an edge on them. Best of all, it doesn't hurt the wallet when you lose or break one.

You could subject a blade to 400 degrees in an oven and that coating would handle it fine. No way to know what was done to the blade prior. The only thing that can make anyone suspicious is the fact that he won't return the pieces of the knife. Very suspicious. I would like to think that he did an honest test. But after watching how soft he was on the skrama compared to the thinner and better cutting busse, I just don't know.

Possibly, I guess I just don't know how high a temperature that coating can withstand.

More importantly though, what is the tempering temperature of INFI? It's possible that 400° is around that range, but even if that was done, wouldn't that make it softer and tougher rather than harder and more brittle?

Either way, I really can't see him doing any of those things. I think the simpler reason for him not wanting to send the pieces back is that he just doesn't want to bother going to the trouble and cost of sending it back because he obviously doesn't care about the cost of the knife. Perhaps it also helps maintain his image that he's some sort of "destroyer of hype and revealer of truth in the knife world" and since he obviously enjoys the trash talking, having the knife revealed to be defective and then having to come back and possibly test again and show it does well on the 2nd round would greatly minimize the interaction on his videos. I think he really enjoys all the drama and thus traffic it's driving to his videos right now. Losing that drama is counterproductive to his goals.

I have yet to go watch that Skrama test video so I'll have to go do that now. Thanks for the reminder!

Good question. I don't know what the tempering temp would be but just looked up Bohler K329 which is very close to INFI here is the tempering graph. So it seems you would have to really cook INFI to a high temp in order to ruin it's temper and years ago I remember Busse saying as much

I think I’ve read years ago that, after the 60 hours of cryo treatment, Infi is subjected to a high temperature temper (the exact temperature I dont know. 900F??? 1000F?????).
 
I would interject that the claimed steel of any random Chinese brand is useless information.
Not only do we not know if they are what they claim but ANY steel can be ruined.

He actually keeps the framents and have used them to make "zombie blade"(framents welded back together) to destroy again.
For instance, he once made a zombie steel eagle (TOPS)

I think you are onto something. Perhaps his videos should be played in reverse?

425 will not affect INFI but 500 will.

So, I quoted jerry from a 2022 thread on dlc coatings. So it seems that modern INFI can be affected by temps above 500. However, back in 2000 he did state that INFI would only be affected by temps over 950-1000 degrees. In both cases he advised to keep the steel cool. It's impossible to tell if when grinding your steel is at 400 degrees or 900 degrees. Both will burn skin and neither may discolor the steel.

“As for INFI and temperature extremes, it is amazing. INFI is tempered at nearly 950 degrees. It does not begin to lose any significant hardness until it is held above 1050 degrees for a considerable amount of time. I have to believe that it would need to be extremely mishandled in order to do any noticeable damage.

Most of the simpler high carbon steels (of which INFI is NOT a member) can be drawn down in temper in a matter of seconds if the temperature hits above 500 - 800 degrees. Along the thin edge of a knife, a buffer or dremel can produce this level of heat and can cause serious damage if not executed by a professional. Always check the grade of steel and heat-treat specs. before assassinating it with the dremel tool Uncle Leo gave you for Christmas. Always keep the steel cool to the touch and you should be fine.” –Jerry Busse

So just to weigh in on a few things.

I haven't watched the skrama video which I'll have to do but it's nearly impossible to tell equivalent effort with different knives. Back in the day when I did table of destruction videos I would hear that all the time- it just doesn't work that way.

I have also been accused of ruining ht before a video or sabotaging videos. For 1 ruining the heat treat would ruin the coating and finish, and for 2 it's just plain silly. This is subjective based on my experience but knowing the effort that goes into a video like this, not just with the filming and the camera angles, as well as the editing (the worst part) the idea of sabatoging a test is just silly. Like, how much would a person have to be paid or be motivated to do such a thing? It's just not realistic.

Not to mention that something like that could likely be found out and once it was it would totally ruin a channels reputation.

In fact someone in this industry doxed me and threatened my wife and kids and has his massive following report every post and video i make, thank goodness for common followers right, and if he were on fire i wouldnt piss on him. I STILL would never go through the effort of sabatoging his product for a video. It would just be silly.

Fwiw my skrama got a chip in it from nothing- and the edge isn't straight. Not a fan.

Joe said he would send me good pictures of the grain for an analysis video and I can also post those here if yall like.

well, cobalt enhances high temp resistance , so it is coherent that INFI did lose the cobalt in it.
Honestly, the more I research, it seems that INFI is getting less unique as it is getting closer to other ordinary steels:(
However, I still think Joe just got a fluke judging by the "delaminatin" on the cross section.

We shouldn't assume other,s motivations, we can only judge facts

Nickle adds to the toughness of a steel
like 15N20 with an off the chart toughness
Yet it is gone too, so the last thing standing in between INFI and A8mod is nitrogen and BUSSE heat treatment?
 
Haven't been by this sub in a wee bit - too few hours in a day and not enough free time it seems.

That said, the discussion here had me checking out the video in question and now I instantly regret giving the guy the "click". I utilize YouTube for music and the occasional instructional video - otherwise, I prefer to read.

This was a comment that stuck out to me though: "Bladeforums reminds me of high school and it quickly loses its relevance once you become an adult." The lack of self awareness in that statement is deafening, considering the caliber of discussion happening throughout the comments and community sections.

I won't be watching any of this guys videos. I will however, be buying another Busse. It's been a long while and I've been wanting to get a TGULB forever.

Well, wood chipper steel with 8% Cr and 0.5% carbon, is certainly going to be one of the toughest steels anywhere and that includes against 3v with its .8% carbon. And what makes INFI as great as it is, is the heat treat. The name itself has to do with heat treat. I still believe INFI to be tougher than anything except S7 and S5. And it has better edge retention and corrosion resistance than both.
