Years ago when I bought the CRKT Kaspar/Crawford folder, the guy in the knife store told me that the steel [probably 420] wasn't very good. I remember looking at him in amazement because I thought the knife looked so good and seemed so solid, that I was indifferent to the type of steel as long as it was strong, and could be nicely sharpened. I still have that knife and, although I now have many more expensive knives, it still strikes me as a good looking, well made folder.
However I'm not entirely immume to the obsession which expensive steels, and I would probably no longer buy a knife with a 420 blade. However I'm perfectly happy with steels like Aus 8 and 440 c.
I just bought the BM Bedlam folder, which is made with some expensive steel, but I'd have to look at the blade to actually know what the steel is.[ might be CPM 154 ?] I bought it because it's a very good looking knife and for me, asthetics will always come first. And ,like the guy who started the thread, I've never even begun to wear out a blade regardless of the type of steel.
