  • A knife with an appearance of a pocketknife with a blade or blades that at least two or more inches in length
  • That can be released automatically with by flicking of a button, pressuring on the handle, or flipping of the wrist.

There are many types of knives that can qualify a switchblade, such as gravity knives, butterfly or batanga knives, spring blades and snap blade knives.

Legal Defense for PC Section 21510 Charges

California PC Section 17235 provides an exact description of a switchblade and in case the knife lacks the characteristics of the legal definition, defendant can’t be held criminally liable.

The burden of proof is on the prosecutor, but defendant will have to show some evidence that the bag, coat or car belonged to another person.
