Apparently, there are
no limits on the blade length of a concealed carry folding knife in California!

Note that it's from 2002, but I did a little online research the other day and couldn't find anything that contradicted the article -
but you need to check yourself. (I couldn't find any San Diego ordinances against knives, but some cities have them, so check!)
IIRC, as long as the knife is:
- completely concealed when folded and carried
- has a detent or "bias toward closure" (see the web article), and
- may only be opened with positive manual pressure on the blade (eg using a thumb stud attached to the blade for one-handed operation is ok - but no springs and it cannot be weighted towards opening)
you can carry practically anywhere,
including the University campus!
Note that you should check the laws yourself or, better yet, have a lawyer do it! This is not legal advice! I'm not taking the fall for you! In fact, I don't even exist! There is no spoon! FNORD
More seriously, while pepper spray does have the advantage of distance, up close it's essentially useless. I believe that, if you cannot carry a handgun, you should carry a long-bladed knife - other physical weapons are much less likely to stop an attacker.
With all due consideration towards your physical training, this is even more true for you specifically as a woman. Consider grappling with your (probably male, larger, and stronger) assailant, and trying to swing a bludgeon overhand to hit a small target like the head, versus thrusting a knife into the attacker's midsection. The knife thrust requires less freedom of movement, less accuracy, and less physical strength. Even if you cannot reach a vital organ, the pain and blood from a cut in what you
can reach is, imho, more of a deterrent to him than a bruised thigh or arm.
So my recommendation, for what it's worth: both pepper spray
and a long bladed folding pocketknife (as well as
the training to use them effectively). Of course, I hope you never need to use them.
Good luck!
