California Penal Code 17235 PC defines switchblades as a knife that appears like a pocketknife and has a blade(s) at least two inches long that is automatically released by:
- a flick of a button,
- pressure on the handle,
- a flip of the wrist,
- another mechanical device,
- the weight of the blade(s), or
- any type of mechanism whatsoever.1
Switchblades are not knives that open with one hand using thumb pressure applied to – or a thumb stud affixed to – the blade as long as the knife has a mechanism that either:
- gives resistance that the holder must overcome to release the blade, or
- biases the blade back toward being closed.2
Other names for switchblades are automatic knives, ejector knives, pushbutton knives, Springer knives, switch knives, or flick knives. Furthermore, switchblades also include:
- Spring-blade knives,
- snap-blade knives,
- gravity knives,
- “balisong” or “batanga” knives (a.k.a. “butterfly” or “fan” knives).
California law makes it a misdemeanor to carry a switchblade, punishable by up to $1,000 and/or up to six months in county jail.3
