Those are two different groups, as far as Larrin tests, he said he was using spy27 stock that was not heat treated and not formed into knife blades. That makes the results irrelevant to blades processed by spyderco. You seem to not understand the drastic changes in properties of steel between the cold rolled state, and being hardened with heat, and then tempered with heat. Just a few degrees for each of those steps can make a big difference in the characteristics of a blade. As well as the mixture that is being quenched into. That is why I am saying taking steel blanks and not understanding spydercos heat treating and forging process would give results that are inaccurate.Deadboxhero wrote: ↑Sat Jan 28, 2023 4:57 pm
Articulate what the speculation is it is difficult to have a discussion about what you think is going on versus what's actually going on.
Are you saying that how Larrin had he treated something company A would get a drastically different result based on what? And what would the difference be?
Contextualize your thoughts.

looking at elements added and subtracted compared to another steel, are about as uncontrolled and far into the anecdote group as it gets. Thats why at the beginning of the thread I stated I wanted actual experience of using the knife, not those two groups that I outlined are not relevant.
The CATRA study wasn't about adding and subtracting steel chemistry wt% to see differences. Thats not how we understand how things work.
I disagree, I'm interpreting what you're saying (correct me if im wrong) is that the CATRA test was just as uncontrolled as getting anecdotal accounts from the public?
Geometry is one of the most powerful variables.
Those blades were all at the same geometry and sharpness closer than anything we have gotten in any previous edge testing looking at such a high volume of different steels.
Like I said before it's important to have both control testing and anecdotal accounts.
I'm not trying marginalize anecdotal accounts.
However we would be at a huge loss to the community if we try to marginalize controlled testing.
As for anecdote, someone obererving their experiences of using a knife, how it dulls, and how it responds to different sharpening systems is not an anecdote. An anecdote would be "30 years ago my uncle had a friend who had a blade with cpm spy27 and he could cut doors off cars with that knife, and it was always shaving sharp"
See the difference?
