A samurai sword is made of excellent-quality steel that is repeatedly heated, hammered and folded. The repetition of the process ensures the removal of all air bubbles that can form in the steel (which weakens the sword) during heating.
Whenever there is any discussion of historical warfare and the importance of sword-fighting skills, the word “Samurai” always seems to enter the conversation. For hundreds of years, heroic tales of the unmatched bravery of the Samurai have been delivered to the ears of eager listeners around the world. The combat skills of the legendary Samurai are greatly complemented by the strength of the swords they possess.
To achieve an optimal level of cooling, a thin layer of clay (a combination of ash and water with the clay) is applied on the cutting edge of the blade to cool it down, keeping it sharp and hard, while on the other edge, a thicker layer of the same clay is applied to make the sword sturdy and shatter-proof—essentially providing a sturdy backbone.
This is why iconic Samurai blades like Katana or Taichi are generally curved, since the two edges cool at unequal rates!
“The sword embodies the soul of the Samurai wielding it.” This aphorism aptly summarizes the Samurai sword. Katana and other Samurai swords are indeed majestic-looking weapons with all the strength that a piece of steel can provide, in addition to the patience and care of a master craftsman. What more could you ask from a sword of such legendary stature!
