Plain edge Endura 4, Leatherman Wave with a badly chipped straight blade and some of the screwdriver tips also chipped by the previous owner, and a Derma-Safe razor blade tucked inside my wallet for the times when I need a *really* sharp knife.
The leatherman mostly only gets used for the pliers. When I need a blade, I pull out my Endura.
Plus, if you count "carrying while at home", my HI 18" Ang Khola. Stupid Canadian laws against carrying weapons.
