Pro - if you're using it for self-defense applications you now have two sharp edges and for some folks that's a plus.
Con - if you see the knife as a tool with edged-weapon potential, the sharp clip will get in the way if you're one of those folks who uses the spine as another handle.
In the city we do not baton a lot, at least not on the back of our knife

You wanna baton on a recalcitrant idiot, just make sure the traffic camera is pointed the other way.
But I do use an RC3 or an Izula (loving that little pink bastard more daily) fairly constantly and the back of the blade being sharp would be a hindrance for me in that capacity.
I'd like to give one a shot anyway, just for a change, but in IL or in many places I tend to spend time, a sharp false edge or double edge makes the knife a dagger in legal terms, and I just do not need the hassle.
I may well snag one with the false edge and then dull it off, which would avoid the dagger issue, but still give me the improved profile for "milinja" taskings.
Milinja is a term encompassing mall ninja which I made up. Feel free to use it.
