I like RWL-34 as it is the closest to 01 but without the need for as much attention. As I'm in and around salt water a lot, it made more sense to use RWL on the DB. You can't beat the patina and character that tool steel develops through use though.
I used to edc Fällkniven U2, but found it a bit small and pain in the donkey to sharpen. Switched to a tenacious, don't quite yet know what to think about it. And then there is my beloved Opinel carbon folder. Just love it, although I don't carry it as much.
My puukko that I usually carry when in a need of a fixed blade was made by a chap in country, don't now what carbon steel it is, takes a wicked edge very easily, needs re sharpening after any significant use, rusts if not oiled. Blacksmith forged blade, waxed birch handle of perfect shape and proportion. Truly an extension of my hand. Had it 20 years now, and even though I have plenty of other knives and puukko, it's my go-to favorite. A true scandi grind (and therefore I will not be cutting any heavy bone with it )
