The Art of Nihonto – Guide to buying the Japanese sword

 

Preface

 Samurai’s history is a profound, eloquent legacy of ancient Japanese warriors in which millions of people worldwide are being fascinated. Samurais themselves played the most significant role in this thing- They went from the imperial army to reconstructing the whole system and reigning Samurai’s country for over seven centuries. Thus, one of their primary weapons, Katana (Japanese sword), began to have many important meanings attached as times went on. Katana is still deemed one of Samurai’s most significant cultural heritage in today’s Japanese culture.

To those who have yet to discover the real value of the Japanese sword “Katana,” – this article is for you.

 

Katana is beautiful

 The Japanese sword is the kind of art that has grown over history. Swordsmiths over the years would make minimal changes to the blade’s curvature, the Hamon, length, width, and all the other detailed features to please the sword’s owner and let the sword hold its own identity. That is why Katana has become so beautiful. In every part of the blade, you see the swordsmith’s intent and Samurai’s love and aspiration for Katana.

 

Attention to Detail

 Above brings us to the next part; the detail.  It gets more important as you learn more about Katana. The blade’s significant features such as Hamon, the size, type of curvature, other segments such as the handguard, the grip, the scabbard, and the list goes on and on. One can only build a gem-worthy Katana when all these segments are put together deliberately. To see the monument of tremendous work by the swordsmith – It is legitimately an eye-opening experience every time you learn something from it.


 

Style

 Blacksmiths regarding Katana were known to have had individual styles in their work. The five most popular ones were Yamato-Den, Soshu-Den, Mino-Den, Yamashiro-Den, and Bizen-Den, branching out to countless other swordsmith schools.

 They differed in the blade’s design, the texture of metal, shape, etc.

 

Katana Is the Reflection of Samurai’s Life

 Last but the most significant of all, Katana represent Samurai’s lives in the past era. The signs and artworks in Katana are believed to have been based on people’s religious/philosophical views. If you take a close look at it, you can tell that every Katana has a story to tell.
