Check out this statute, which covers the property -- including dorms -- of any university (public or private) as well as K-12 schools:

(4) It shall be a misdemeanor for any person to possess or carry, whether openly or concealed, any BB gun, air rifle, air pistol, bowie knife, dirk, dagger, slingshot, leaded cane, switchblade knife, blackjack, metallic knuckles, razors and razor blades (except solely for personal shaving), and any sharp-pointed or edged instrument except instructional supplies, unaltered nail files and clips and tools used solely for preparation of food, instruction and maintenance on educational property. Any person violating this subsection shall be guilty of a misdemeanor and, upon conviction thereof, shall be fined not more than One Thousand Dollars ($1,000.00), or be imprisoned not exceeding six (6) months, or both.

Scissors that are "instructional supplies," or that are used solely for "instruction and maintenance," are excluded, but what about other scissors? Or anything else with a sharp point or an edge? Yow.
