Historically, katana were one of the traditionally made Japanese swords that were worn by the Samurai class of feudal Japan, also commonly referred to as a "samurai sword". The katana is characterized by its distinctive appearance: a curved, slender, single-edged blade with a circular or squared guard and long grip to accommodate two hands. It has become renowned for its sharpness and strength.
The Katana was the standard issue sword of high ranking Japanese officers in the Army and Navy. It was always a fearsome weapon to behold to many non-Japanese. Many officers who lead their banzai charges would wheel their katanas as a rallying cry. Unfortunately this allowed the Americans to zero in on the officers and shoot them down.
The Katana was the standard issue sword of high ranking Japanese officers in the Army, and saw action on nearly every battlefield. To those in the lower rankings of the army, having such a weapon was considered a source of pride.
