I do love ZDP. No question it's my favorite stainless steel. Overall I like CPM M4, and even ingot M2 better for folding knives, and smallish , medium duty fixed blades. I seem to be able to get the super sharp, biting edges I like on these steels much easier than any other that compare wear resistance wise.
I've thought long about this and I've come to the conclusion that I really like the tungsten steels best. Vanadium carbides are harder, but overall, I like the whole package the tungsten steels give. With CPM M4 and M2 there is moly and vanadium as well and they do their part.
I've figured out that's why I like vascowear better than the similar, but all vanadium carbide CPM 3V. The Blue steels also can take some wicked edges that I like too.
Yes, ZDP is still a great supersteel that has greater performance than most high carbide stainless steels when it comes to thin, but strong edges.
