I'm sorry - your sarcasm is lost on me. As is your point - I thought you didn't expect any knife should be tested to destruction (or more correctly, such testing is stupid)? Are you qualifying your objection to destruction testing to S30V and similar (i.e. it's okay for SOME types of steels)?? Steel bigot
No sarcasm here. I think it's truly fascinating that (apparently) you have to be able to pass a 90 degree bend test as a part of your journeyman test. I'm truly curious as to what this test is measuring.
As for steels, my layman's understanding is that some steels are soft and springy, while others are hard and brittle. So I would therefore expect some steels to do better at a 90 degree bend test than others. Is it steel bigotry to expect this?
My expectation is that S30V is going to tend towards the hard & brittle end of the spectrum because it is a stainless steel. So I would therefore expect S30V to, for example, break easier when pounded on with a steel mallet than if a high carbon steel was in use.
On the other hand, if I was living in a very humid environment, I would expect S30V to stand up better over the long run than that high-carbon steel. So if you live in, say, Hawaii or Louisiana, then a knife like the Green Beret might be for you!
In the end, you have to purchase the tool that works best for your intended application. I wouldn't expect there to be any surprises there.
I've mentioned up-thread that I don't own a Green Beret, nor do I have any desire to own one. One reason is because it is made out of S30V, which I shy away from in a bigger knife simply because it IS a stainless steel. I live in a very arid environment, and so I can't imagine a reason why I would want a knife in this format made out of stainless steel, unless I was going to use it a lot for food prep.
In other words, I am not at all surprised that you can get a S30V blade to break by beating it with a steel 3 lb mallet. It's a stainless steel, and so I don't expect it to stand up to that kind of abuse in the same way as a non-stainless steel might.
As to whether the Green Beret is truly "Green Beret tough," I suspect the right way to find that out is to go ask a bunch of Green Berets if they use their graduation gift on actual missions, and if so what they think of them. The fact that the Green Beret is still being handed out to Special Forces Qualification Course graduates, and has been since 2002, tells me that either the knife is doing well at it's assigned task, or graduates aren't using their graduation gift on actual missions. Again, in order to know how tough the knife actually is, one should ask people who are actually using it for the task that it is designed to perform.
I think it would be most telling if you asked 100 Green Berets if they were using a Green Berek Chris Reeve knife on an operational basis. If the answer is 'no', then the follow-on question ('why?') well tell you all you need to know about the knife.
