This for real?

No ideas. Looks real enough. Is that supposed to be one of the Ontario blades? If so, Ontario no longer makes the RAT line-up.
 
My guess is he broke the HT by red heating the blade and maybe quenched it without tempering. But I'm pretty positive he messed with the HT.

Even cheap chinese/pakistani knives are tougher than that.
 
How do you break the HT without frying the factory coating and stencil on the blade? Looks like nearly NIB at beginning.

Just curious but how are you positive the guy messed with the heat treat?

Just because a knife broke that means the heat treat had to be altered?

In fact I am "pretty positive" he did nothing to the heat treat. Heating a blade up to red hot and quenching it burns off anything on the blade and makes all kinds of scale. The blade appears to be still coated and at the very least still has the laser (?) etch of the company logo. That would be long gone if heated up to red hot. And if he heated it to a lower temp that would not have messed with the blade coat it would have made the blade softer and MORE prone to bending.

I am amazed at how many people around here blame things on a bad heat treat. It is pretty ridiculous. Knives are heat treated in large batches and if there were as many claimed bad heat treats as there are around here then half of the production knives would be crap.

I can see a knife getting too hot during final sharpening and messing up the temper at the very edge. But this is not a 'bad heat treat.'

There are other reasons a knife can fail or have something wrong with it and it gets old reading about all the possible "bad heat treats" that gets thrown around on here.

For clarity, are you saying that that is a legitimate example of the performance of those particular blades? I think it's fairly reasonable to presume that something went wrong and that probably isn't representative of the performance of the entire line. A problem with HT seems like a reasonable initial guess, though certainly one video isn't definitive to determine that. One might suspect that if the entire line performed that way, Ontario would've been called on it long ago.

I'm not sure why anyone would assume that the user had anything to do with the problem though. It looked fairly unused at the beginning of the video to me.
 
Im not an expert on this but i just dont see how whacking the spine with a piece of wood straight up broke the knife. And another thing is the guy looked like he knew it was going to happen?

Of course, he filmed it.


A baked epoxy coating is very tough. I wouldn't be surprised if it could resist a torch. That's what makes me thing they did something to the blade.


Come on. You've seen noss' vids, a blade can take more than that. A lot more. I wonder what he would say about this ;)
 
There are very few production knives that can survive being put into a vice and pulled to 45 degrees. There are a FEW custom makers able to heat treat that can survive 70 - 90 degrees. Goddard is one, Crowner is one. There are a few others.

I defy anyone to show me a production model that can survive a 70-90 degree bend.

Sorry guys, you can blame it on Ontario if you want, but the other RAT's are not going to pass the vice test either.
