My EDC's are:
Vic Farmer (Soldier with saw)
Vic Camper
Vic Nylon Solo
Opinel #8, #10 and at some point a #12
Buck 110
Byrd G10 Meadowlark
Vic Classic with LED (Often paired with a larger folder, especially at night)
My uses mostly revolve around the outdoors and the kitchen. I use my Opinels more than any other knife around food. Carbon steel hasn't been a problem with that. They chop up carrots, apples, onions, chicken, ham, fish, canteloupe, watermelon etc. I often prepare chicken teriyaki or elaborate pastas using an #8 or #10. If I'm ever eating and need a knife, my EDC gets used for that too. Opening mail and packages. On the rare occaison I spend money on something, it'll open it up too. CD, DVD or something in a blister pack. In the outdoors my folders will see chopping, batoning, whittling, prying off bark, drilling holes into wood with the tips, digging through soil and cutting roots, dissecting bugs and being a general poker and scraper to examine things like moss or fungus.
I really like saw-based SAKs, of which I own three. Very versatile in the outdoors. The Buck 110 is very comfortable with a classy look, wooden scales (My preference) and a well-done hollow grind. The Vic Nylon Solo is a very nice sub-10$ slipjoint with more generous blade length and thickness than a normal SAK. Grippy scales too. I reprofile all my folders to acute edges, sometimes grinding flat to the stone, usually grinding just a few degrees above flat. No secondary bevels.
