In India, it is generally not illegal to own a sword, but publically carrying one without a proper reason or permit can potentially land you in legal trouble. Laws in India concerning weapons are primarily governed by the Indian Arms Act of 1959.

The Act does not specifically mention swords, but it defines arms as articles designed or adapted as weapons for offence or defense. This broad definition could potentially include swords. Therefore, carrying a sword in public without a valid reason could potentially be seen as a violation of the Act. However, the enforcement of this law may vary significantly based on local interpretations and practices.

For specific, up-to-date advice, you should consult with a legal professional or contact local law enforcement or legal authorities in India. It's always important to ensure that you're in compliance with local laws and regulations.
