Understanding the differences is essential for those seeking authenticity and historical value.

What is a Nihonto?

The term Nihonto refers to traditional Japanese swords forged in Japan using artisanal techniques passed down through generations. These pieces meet strict standards in terms of materials, forging process, and steel treatment. They are often registered and accompanied by official certificates of authenticity issued by Japanese organizations such as NBTHK or NTHK.

Each Nihonto is unique, with a distinctive hamon (temper line), blade shape, and mount details. Its value is not only aesthetic or functional but also cultural and historical.

Modern Japanese swords

Modern Japanese swords, while they can be of excellent quality, do not meet the standards that define a Nihonto. They are produced using industrial and semi-automated processes, employing modern steels and techniques that reduce time and cost.

These swords are ideal for practices such as iaido or tameshigiri, as they provide functionality at a more affordable price. However, they lack the historical character and official recognition of Nihonto.
