i have a David Farmer necker i really like with a 2 7/8" blade, 1/16" thick with a 3 1/2" handle.
or an ESEE Izula.
also have an EDC/Utility knife rom Mitchell Knives with a 2 7/8" blade and a 4" handle that would be fine as an only knife.
for a folder i used to carry a Spyderco Delica. sorry, while a Ladybug is fine for something extra on your keys, it's not what i want for a solo EDC.
i've got a "pocket fixed blade" from Towbin Smith with a 2 1/4" blade and 3" handle. the kydex sheath is made for pocket carry. it doesn't get carried as the only EDC knife tho, but it does get carried frequently. wouldn't really feel inadequate if that was all i had.
a Krein pocket bowie would be nice, but a Foit minimalist or a Vox Gnome might be too small.
a Fiddleback Runt would be OK
myy county has a silly ordnance that prohibits concealed carry of any knife with a blade over 3". since i CCW and have my shirt untucked that means that anything i'm gonna carry at the belt line needs to be under 3". however, i carry a ST-2-- with a 4 blade, but the pocket clip is visible, so it's not a problem with the BS reg.
