California Legal / Mini OTF refers to a specific category of automatic knives that are legal to possess and carry in the state of California. These knives are compact in size and have an Out-The-Front (OTF) mechanism, meaning the blade is deployed by sliding it out of the front of the handle. The term California Legal indicates that these knives comply with the strict laws and regulations regarding blade length and deployment mechanisms in the state. Mini OTF knives are particularly popular due to their small size, making them convenient for everyday carry while still maintaining the functionality and reliability of larger OTF knives.
