In California, carrying a fixed blade knife is legal only if it is carried openly in a sheath on the waist. Concealed carry of fixed blades is illegal and can lead to serious legal consequences. Switchblades with blades over 2 inches are prohibited. Folding knives are generally allowed to be carried concealed if they are not automatic. Local ordinances and specific locations may impose additional restrictions. Understanding these laws is essential for lawful knife ownership and carry in California.
