I like H-1 because it is the ultimate low-maintenance steel. And in an SE package like the Pacific Salt, it becomes the ultimate beater knife for me. It's a knife I'm not afraid to push to the maximum, maybe even abuse a little bit.
H-1 is also super tough and very easy to sharpen. In SE it is a super steel, no doubt about it.
I like CPM S110V for its incredible edge retention. It is more difficult to sharpen than most, but once you're there you can be confident of having a sharp working edge for practically forever.
Super Blue is one of my new favorites. It's just so much fun to own and use this steel. First off, I really like the way it shows use with a patina. I know that's not everyone's thing, but I just like the look of a well-used knife.
Second, this steel is a breeze to sharpen. The factory bevel on my Calypso Jr was probably something like 40-45° inclusive, so I reset it to 30° inclusive, finishing with a few strokes at 40° with the Sharpmaker UF rods and a few passes on a diamond paste strop. I have never had a knife so sharp - it whittled hair, sliced through a paper towel like copy paper. It's a fairly thinly ground knife, so Super Blue really shines in this configuration.
I was initially worried with rust, but I've been carrying this knife for a week or two now and my confidence in its EDC capabilities keeps growing. No problems with rust, even after cutting up some pretty acidic fruit and just rinsing the blade off with warm water. Of course I am careful not to get too much moisture in the pivot area but I do that with all my knives that aren't Salts.
