The legality of walking around with a sword, or any other type of weapon, in public areas depends on the laws and regulations of the specific jurisdiction you are in. It can vary significantly from country to country, state to state, and even within different localities.

In many places, the carrying of certain types of weapons, including swords, in public areas is restricted or prohibited. These regulations are typically in place to ensure public safety and prevent the misuse of weapons. Laws regarding weapons often consider factors such as the type of weapon, blade length, purpose, and the individual's intent.

It's essential to research and understand the specific laws and regulations in your jurisdiction regarding the carrying of weapons, including swords, in public. You can consult local law enforcement agencies or legal professionals to obtain accurate and up-to-date information on the laws that apply to your area.

Even if it is legal to possess or carry a sword in public, it is generally advisable to exercise caution, respect local customs and norms, and ensure that the sword is properly secured, transported, and stored in compliance with any applicable regulations.

Remember, the primary purpose of weapons like swords is usually for display, historical/cultural purposes, or martial arts training, rather than for general public carry or self-defense.
