The+Katana

The katana (also known as the samurai sword) was created in the Kamakura period of feudal japan, being modified from the tachi, and was more sleek and compact than its predecessor. These swords were a part of millitary usage until the end of World War Two. Forging the sword required a special Japanese steel called Tamahagane, a special mixture of both hard high carbon steel and tough low carbon steel. Simply sucessfully forging and crafting the sword takes over a year! (Odd how many samurai existed.) Misusing a katana can cause irreparable damage to the sword, so keeping it well oiled will keep it from being damaged and rusting.
