What is the best/most intimidating SOG knife for self-defense?

I go to college in the city and especially in certain areas it isn't safe but we're not allowed to have CC firearms on campus (this is in Ohio). I want a knife to at least make myself feel better, I realize I would probably get shot anyway. I had a SOG but it fell out of my pocket. I want a new one that's very intimidating looking and good for self defense. I think switchblades are frowned upon by Ohio law so I guess I should get spring assisted. What models are best? Any other advice? Thanks
