I no longer carry a folding knife for defensive purposes. I do not believe one could be employed effectively in majority of likely circumstances in which I would not have a better weapon.

plus pulling a knife, gives your opponent the right defend himself and to shoot you

Not if he is the aggressor or committing a felony. That is why a burglar can never claim self-defense unless he is fleeing the property and was pursued resulting in his needing to preserve himself from lethal force. A knife is lethal force and should be treated as such. If you only use to prevent your death or serious injury you are within your rights unless you were doing something pretty awful to begin with.
