The history of the Japans swords dates back to very early days when swords were designed simply in a straight way. But through the period the art of sword making developed and new techniques were used to design it that was brought from China. The ancient people of Japan also used wooden swords to defend them selves. Amakunia a Japanese smith, according to ancient legends was the one who invented the sword and by the 10th century the folded steel process was used to design the single edged sword. And with changing times the design and the curve of the blade changed and tended to move up the blade. The sword was a warriors pride when he rode on horseback and fought wars with it defending himself and attacking his enemies with a sword that was considered the most efficient weapon of the time. The curve of the blade helps in the downward force of the cutting action.
The katana sword is worn suspended with the cutting edge down and was part of the uniform of a warrior. People carried the sword thrust in their belts with the edge up and anther sword called Tachi, was worn slung across the left hip. And the signature of the designer was splashed in the side of the sword and it was worn so the signature was visible on the front and this helped in recognizing the development and function of the sword. Later on the japans Samurai found that their Samurai swords were prone to damage when used to protect the armor suits of their enemies and this is the reason that the Japanese Sword smith started to use thinner templar lines and they also started making blade that had a thicker back and bigger points.
