Carrying them hidden is legal for most knives. Walking stick knives, lipstick knives, belt razors, razors, and other deceptive knives. Undetectable knives (such as those that don't activate metal detectors) are illegal. Penal Code 20610 PC is the California law that makes it a crime for a person to manufacture, import, sell, give or possess a lipstick razor (“LCK”).
Any knife or blade that is disguised to not look like a gun is also illegal in California. This includes cane swords, knives with belt buckles, lipstick knives, air caliber knives, writing knives, etc. Blades that are undetectable to metal detectors (for example, the other descriptions in statues that talk about daggers, stilettos, daggers, etc.) are obviously intended to be very ambiguous when related to knives in general. However, there are certain limitations as to the types of knives that may be owned by people in the state.
The knives that people can hide carrying are hunting knives, spring knives (automatic knives) and all other knives (in addition to those prohibited). How does the right to have bare weapons from the Second Amendment translate into the right to carry extremely deadly weapons but not potentially harmful knives? However, California courts have determined that butterfly knives fit the definition of automatic razors. The only way law enforcement can determine the true use of knives is when these cases go to court. Glen Mones I'm from CT I have a 2″ K bar, the one the police use as a defense, if someone tries to get a service weapon there, I can carry it, it's not a folder because I recently got into trouble carrying my karambit, I learned the hard way I collect knives, all the weapons, thank you for helping me keep in touch.
If people don't use certain knives with malicious intent, they can freely carry them in an open and hidden way. I would say yes, if you're a small child, you're too inexperienced to play with knives or guns until the person has the proper experience with a knife, you shouldn't play with them. There is a slight difference between the knives that people can have and the knives that people can carry. These knives are usually more than two inches long and include knives that metal detectors can't detect, deceptive knives (cane knives, zobi-tsue, belt knives, frying pan knives, pneumatic caliber knives and lipstick knives), daggers, stilettos and ballistic daggers and knives.
This means that it is a valid legal defense for a defendant to say that, while he may have committed an illegal act under Penal Code 20610, he did so with something other than a lipstick knife.
