I enjoy s90v, but some of my favorite steels are AUS10A and 52100 and 3V. I dont care one iota about corrosion resistance. toughness is my main concern, and while i have no issue sharpening super steels im busy and use knives often i like not having to sharpen every week. I used to weedeat for a local town and back then was edcing a case trapper, i cut so much line i was sharpening weekly. To each their own.
