I'm looking for a new knife with a 3" blade length. Apparently University policy outlaws anything larger than that (I had thought it was 3.5"). I refuse to walk around completely unarmed, so I need a new knife that I can carry without having to worry about getting hassled by any of the numerous campus police who never seem to have anything to do but give students a hard time. Any suggestions for a good blade? I'd like to keep the price point under $50, and I prefer a plain fixed blade, especially for a knife so short. Also, laws in my state prohibit double-edged blades, otherwise I'd just carry a push dagger and be done with it.
