My first choice would be a Microtech SOCOM, second choice would be an AFCK.
The subject of technique has come up here too.
One thing to remember is that in order to stay clearly within the "self-defense" category you may only slice the appendage that is being thrown at you.
Example: Someone throws a brass-knuckled punch at you... the only thing you should cut is that particular hand and arm. Don't duck the punch and stick him in the gut...its no longer self defense after that.
In the above scenario this "slicing" serves several purposes.
1)If you only use slicing motions, there is little chance you'll make the lock fail.
2)Keeping with the "proper" tip-forward grip will keep the tip out in your field of view and possibly prevent your accidentally jabbing yourself in the thigh... or worse(Yikes!), opposed to an "ice-pick" type of grip which points the tip down, out of view and generally aimed back in your direction.
This stance could be argued relentlessly, but there is no disputing that it is the "safest" mode for those who are minimally skilled.
3)Slicing the arm(tendons) will quite possibly render it useless... At the very least your attacker will think twice about sending it back in your direction again, and that is after all, your objective.... or it should be anyway.
4)Again, if you only strike at whatever is directly trying to cause you harm you stay well within the bounds of "self defense". This tactic would even be "safe"(legally) if your attacked by bare fists. (Theres no such thing as a fair fight.)
5)Depending on the circumstances, if you poke your attacker in the chest/stomach/neck your actions could be viewed as "offensive" by a court of law and might actually land you in jail.
6)Lastly, Make certain that whatever knife you carry/use is legal, otherwise you leave yourself open to a whole other nest of problems should you ever have to use your knife for defensive purposes.
