Colonial Knife Corp. has distributed a list of states where it is legal to possess switchblade and automatic knives (sometimes with restrictions). Colonial has thrown some of their model numbers into the list–well, they did provide it! The photo above is the Blackie Collins-designed model 103.
Knife Rights Foundation, Inc. is a 501(c)3 that lobbies in statehouses for your legal rights to possess and carry knives. They are mentioned by Colonial in the guide, and I suspect that is from where the information came.
My caution here is that it is incumbent upon you to research your own state’s laws to determine the legality of any weapon you might carry. Colonial’s guide, and my reprinting of it here, does not constitute legal advice. Enjoy.
