I have searched the site and did not find anything specific to my question. This question is for anyone who lives in, or is familiar with, the San Francisco area knife carry laws. I have researched the California laws and the San Francisco specific laws. I just want to make sure I understand them clearly. I will be working there for a short time in the not too distant future.

As I understand it, the California law does not limit blade length of a folding knife, only their classifications of a "switchblade" type knife. In San Francisco, the blade must be under 3 inches, but there seems to be some connection to illegal loitering before it becomes illegal.

I normally carry a one hand opening knife, generally a Spyderco. I do have several choices, so it is not a huge deal to me, but my co-workers may resist the restrictions. My intent is to ensure nobody gets into trouble.

Any illumination on the legal climate in San Francisco as it relates to pocket knives and tools would be appreciated.
