The officially licensed Nintendo Master Sword replica is not available for purchase on the Nintendo website, but many third-party providers carry the item, like Walmart and Amazon. Countless other unofficial Master Sword replicas are also available online. Some people have even made real swords designed to look like the Master Sword. For the purposes of carrying around a replica in public safely, it is generally better to pick one of the many options that are not real weapons. If you are an avid collector of real swords and weaponry, you might still want to consider adding a realistic Master Sword to your collection for display.
