Second Amendment does not clearly apply to dirk knives and daggers under California law.
What knife laws (statutory law) mean is about more than the legislated law in the United States. Judicial opinions (case law, common law or judicial precedent) are considered "law" with the same force as statutes. Here are pertinent case law summaries that provide helpful information on how knife laws in different states have been handled or decided by the court system. We include valuable notes for the knife owner. For attorneys representing knife issues we offer suggestions from an experienced criminal lawyer.
