For general, all around use, what is your most liked steel.
Mines S30V just because I like the edge holding, and I don't have enough spyders in other steels. Holds an edge, stain resistant, it's qualities have been lauded I'm sure.
My runner up would be CPM D2 though.
S90V. I'm pretty performance driven in my preferences, and for what I do, wear resistance is the top trump card. When they come up with something that will carve concrete and still shave, I'll be carrying it.
60 Nitinol PM yab?
Although I've hard it's high hardness makes it quite brittle.
For general EDC I prefer CPMD2, I'm able get this much sharper than S30V, and have encountered no problems with it taking a fine edge. Much better edge retention too.
I actually find it easier to sharpen than S30v too (most of my sharpening is done free hand on carborundum stones).
Corrosion has never been an issue for me.
+1 for S90V, my para2 cf is absolutely awesome!! Plus Golden can make it sharp again...whenever it eventually wears out
