Not in Ohio.
In Ohio it's legal to "open carry" large knives and even swords. You'll, um... "draw attention," probably unwanted attention, and maybe a "friendly visit" from the local constabulary, but it's not illegal.
We just had a change in our knife laws last year. It was focused around "automatic knives" and "going forth armed" details related to knives but it might have affected sword-sticks/sword-canes. So I can now carry an automatic knife now but I don't know if it impacted a sword-stick. I'll have to go do some more research.
Peace favor your sword,
