The ability to legally wear a sword varies depending on the country, region, and local laws and regulations. In many jurisdictions, carrying a sword in public is heavily regulated or prohibited for the general public due to safety concerns and the potential for misuse.

In some cases, there may be exceptions for certain cultural or ceremonial purposes, or for individuals who hold specific positions or have obtained permits or licenses. However, these exceptions are typically limited and subject to strict regulations.

If you are interested in wearing or carrying a sword, it is crucial to familiarize yourself with the laws and regulations in your specific area. It is advisable to consult local authorities, law enforcement agencies, or legal professionals to ensure that you comply with all relevant laws and requirements.
