No they are legal in CA though in a residence not on property owned by a college or university.BTW...is a katana legal in a dorm room? Seems better than alot of other choices, and would be tough to take away.
Any fixed blade knife is a serious crime on a college campus in the state of CA, a sword is by definition a fixed blade. On top of that it's purpose is soley as a weapon.
any person
except specified peace officers to bring or possess any dirk,
dagger, ice pick, or knife with a fixed blade longer than 2.5
inches on the grounds of, or within,
any private university, UC, CSU, or CCC, punishable by up to one
year in a county jail, or imprisonment in the state prison by 16
months, two or three years.
Doing so would be a felony.
The only knives legal on a college campus are folders that are within all of CA laws.
(b) Any person, except a duly appointed peace officer as defined in Chapter 4.5 (commencing with Section 830) of Title 3 of Part 2, a full-time paid peace officer of another state or the federal government who is carrying out official duties while in this state, a person summoned by any officer to assist in making arrests or preserving the peace while the person is actually engaged in assisting any officer, or a member of the military forces of this state or the United States who is engaged in the performance of his or her duties, who brings or possesses any dirk, dagger, ice pick, or knife having a fixed blade longer than 2 1/2 inches upon the grounds of, or within, any private university, the University of California, the California State University, or the California Community Colleges is guilty of a public offense, punishable by imprisonment in a county jail not exceeding one year, or by imprisonment in the state prison.
In fact under CA state law even knives for use in preparing food if you have an apartment with a kitchen on college property would technicaly be a felony.
