You may want to be very very careful. Give your campus police/security a ring or better yet show up in person and verify with them. Every campus is different and every campus has their own set of rules.
I recently graduated from undergrad at a school in Springfield, MA which is a top 10 most dangerous city in the US. My school had its own police force which were rotated cops through the Massachusetts state police. I never felt I needed to carry a weapon as they constantly patrolled the campus and were actual state police officers. I actually ordered domino's one night and when I went outside the guy was being arrested by the campus police. Dont ask me what this guy did but I got my food free that night needless to say. 8 cops were pulled up, all campus police and had guns drawn. A few of them had shotguns drawn on top of that. I remember seeing them pull a rifle what looked like a m16 out of the guy's trunk but probably was a AR-15 being that it looks like a m16. Not trying to start the gun topic in here but just dont want encourage questioning on what it might be.
You shouldnt have to feel the need to carry a knife around on campus. That can only encourage questioning if others see it. Remember when going to a college, everyone comes from different backgrounds and raised differently. They may feel extra edgy when they see someone carrying a weapon around. At my undergrad, you werent allowed to carry a weapon period. No knives, guns, etc. Hell kids were kicked off campus for having knives on my campus. They werent necessarily kicked out of school but werent allowed to live in the dorms.
Just saying, if you feel the need to carry a weapon in college, you may want to rethink where you go to school. Not trying to stir an argument here but you should feel safe where you go to school considering I am assuming you take everything into consideration where you decide to go to study. Most schools should want you to feel comfortable considering that is where you will live 80% of the year assuming you dont live at home. I am sorry but if I can feel completely safe on a campus located in a city ranked in the top 10 as most dangerous in the country and I didnt carry a weapon, you shouldnt need to carry one either.
