CPM440V comes in first, with ATS-55 coming in a close second. I think these are both good working steels. I've never had a problem with either rusting or pitting.
I've grown partial to my ATS-55, but the best steel I've come across, I've only had in one knife... Pakistan Steel. I've got a 5" lockblade skinner... hasn't touched a stone in 20yrs, and it rivals my spydie for an edge...
We all start with 10 fingers. Those with Spydies have 9 to spare, Still need a thumb. Good thing I still have 8 to spare...
Hi Wolf. I have not yet experienced a "good" steel from Pakistan. At least not in the years I've been involved in knives (more than 40). You have an oddball, IMO.
