Aged steel cuts better??? You are kidding, right?

I love that 'Icecream Headach' move she did at the beging. I get that all the time from a Slurpee.

Well, that is true and false...at the same time.

I at first thought I made a mistake in what I was talking about but after re-freshing my memory on the subject I can't seem to make sense of what your trying to say?????

Kerry, you didn't know about this

I think sunlight also helps. Thats why I've got the knife you made me sitting in the window...it should be good to go in about 10 years:thumbup:

OK, it could be BS, but...

There are some papers written on the effects of aging on steels. Unfortunately, you've got to drop some $ to get access.

It is possible the steel outgasses.

That would explain the writer's time cut-off point.

As for steel being a "soup" of atoms. Seems like that describes a glass more than the crystalline structure of a metal.

I dont have any problem believing that metal, and most everything else, changes over time. I've seen the failures that intermetallics can cause after several years. What I have issues with is a 10 fold increase in cutting with no more explanation than metal changes over time. I'll read the article again when I get a chance, to see if I missed it. If steel changes that much over time, and a relatively short time at that, then it could just as easily cause problems rather than improvements. Again, I've seen it happen in industrial settings, but that was well documented issues at welding temperatures, and the uncontrolled cooling from those temperatures. I'm gonna need something more to accept a 4 to 10 fold increase in performance in any aspect of service.

That was just a little play on words, hinting at the Quantum wave-particle duality.

I finally got the mag and read the article, several times; to try and let in "soak in". It never did.
I want a refund and my time back.........
10 x better, come on.......
Sounds like a complete crock....

I read the article too and I was very skeptical as well. I still am a little bit, but is it possible that over the years, oxidization has caused microscopic serrations in the blades? The author stated that it was mostly the carbon blades that he saw this on and he wasnt doing many trials except for slicing rope. On the oldest blades there was no discernible difference in cutting performance but he had tested those years ago when they had already been old. I know when I worked in a restaurant, my favorite knife was the oldest. It held an edge forever and cut just about anything. It was an old carbon steel blade that had a lot of visible oxidization on it. Just my guess. The author of the article never really stated why he thought they had better cutting performance.

My best guess - No.

Surely any pitting on the cutting edge from oxidisation would be removed whenever the knife is sharpened.

Maybe aged steel is in some ways better, but 10x the cutting performance is way beyond what I would be prepared to believe without some solid scientific testing to back up that claim.
