Blackie Collins turned me on to the Sandvik alloys in 1986. He was sold on them for their ease of heat treat, relatively easy grinding, cleanliness, and fine grain structure, as well as better than average edge-holding(for the time, and assuming proper grind and heat-treatment), and ease of sharpening. He wasn't wrong. I'll take 12C27 over 440A or AUS 6 or even AUS-8A for most applications where stainless alloys might be preferred. 13C26 or 14C28N are better still. I'm not a steel snob, and don't base my cutlery choices on that variable alone, necessarily. Although, given a choice, I might choose a 'trendier' alloy, if I thought I could use the extra capabilities. I do like ZDP-189 for an EDC folder tho...
