What Is an Antique Samurai Sword?
An antique samurai sword is a traditionally forged Japanese blade dating back to historical periods such as:
- Meiji Period (1868–1912)
- Edo Period (1603–1868)
- Muromachi Period (1336-1573)
- Azuchi Momoyama period (1573-1603)
These swords were crafted by master swordsmiths using Tamahagane steel and ancient forging techniques. Most are signed on the tang (nakago) and often include official certificates of authenticity issued by institutions such as the NBTHK (Society for the Preservation of the Japanese Art Sword).
