My BK-14 fits in a pocket sheath that doubles as my wallet (with some bike inner tube sections stretched across it) and at 7" OAL, comes with me everywhere and in jeans, casual attire and even a suit, unnoticed.
A drop point is an awesome all-around shave and FFG makes it a decent slicer.
It can do most utility and outdoors tastes, as well.
If I could only have one food knife, I'd choose a 7" Dexter Russel fillet knife.
For both uses, I guess a cold steel Canadian belt knife or the original Gronholm Canadian knife in FFG could work well.
For DGAF public wearing and / or end of the world... Kershaw Camp 10 is an amazing blade.
