What about KNIVES?
Calguns Foundation Wiki FAQ: What about KNIVES?
Simple answers for simple questions
Discussion: Knife laws
Except for switch-blades and schools, the State does not specify a length for knives.
The State does NOT pre-empt cities and counties from their own knife laws; however, cities and counties can create only misdemeanors and infractions. There can be no local laws imposing a felony for simple possession.
Fixed blades must be carried openly, to avoid a ‘dirk or dagger’ felony.
Folded folders are NOT ‘dirks or daggers’.
University of California and K-12 schools ban all blades longer than 2 ½ inches, and locking folders.
Other Colleges and Universities ban fixed-blades longer than 2 ½ inches.
