here's a link to a site that contains a lot of info, but you can find much more about your state's laws by doing a search on yahoo or something, finding the state's code, and actually looking for knife laws. i had to do that for georgia, and it was tough, but it's the way to go for good info. oh, and there's a link to the switchblade act. http://pw1.netcom.com/~brlevine/sta-law.htm i just thought this was humorous. it deals with people who can carry switchblades. § 1244. Exceptions Sections 1242 and 1243 of this title shall not apply to - (4) the possession, and transportation upon his person, of any switchblade knife with a blade three inches or less in length by any individual who has only one arm.
