As long as it is not concealed, and you don’t carry it onto a school ground or into a public building or airport, you should be OK under State law. (Openly carried in a sheath on your waist is OK, but nothing can cover the sheath (e.g., a shirt tail).) However, there may be some applicable local ordinance. I think that these are all preempted by State law, but there has not been a recent ruling on that.
If it is visible on your belt, yes.
Arnie’s gang in the Republik Of Kalifornistan haven’t banned that yet. But give them a while and they will!
