Just out of curiosity ... the wording indicates no rider for a felon ... yes ?
People who are prohibited from carrying firearms are prohibited from carry concealed and switchblades knifes looks like to me
As I read it, if you are carrying the knife openly, even if you are not able to legally possess a firearm, it is legal.
So it looks like carrying a knife openly would be legal for someone who had a felony record.
I am not a lawyer, nor do I play one on the Internet.
