The Sandvik steels are both easy to sharpen and hold an edge well. They are nothing fancy but they work well. I have knives in 14C28n, 12c27. Both are among my favorite knives. 3V is also popular for user knives. As is 154CM. I also have a custom fb in D2 that is very good. D2 is a little harder to sharpen some say- I've never had any problems with it. It holds an edge very well.
