I have used the Baryonyx Arctic Fox field sharpener almost exclusively recently. Great feedback, nice polish. You get the fine side in a grown up Benchstone as well. For refinement after (if necessary), I recently got back to one sheet of printer paper on the coarse Norton Crystolon side with Flexcut gold applied. I think the first that mentioned it ever was HeavyHanded here on BF. It's a great , clean and cheap way with very good results.
For steels with those crazy hard carbides, I would use diamond plates only and end up with the same stropping procedure except would either use HeavyHanded's new gray compound (that has some diamond content) or diamond spray/paste instead of Flexcut gold
P.s. I am most certainly not a cool kid !
