In that case if you open carry, be mindful if you're downtown in a big incorporated city. Some have municipal codes about knives that are tighter than the state law, and cities even sometimes have laws about open-carry, but permit concealed carry. The logic is they don't people being "menacing" by strapping on big blades. And sometimes if you are openly carrying a big knife is say a grocery store or are hanging around in a commercial area, there is still a possibility of getting hassled a bit by the cops because they will find you suspicious. This can even result in a disorderly conduct ticket even if there is no law be broken just by carrying the knife. Short answer, never flaunt weaponry in front of cops.
But remember concealed carry is fine under state law, so if nobody sees it, there will never be a problem in the first place.
