Kastane is one of Yoshimitsu's weapons in Soulcalibur IV. It can be bought in Character Creation for 7,000 Gold after completing Story Mode with Yoshimitsu. A Sri Lankan curved sword. It is intricately decorated and at first glance looks like it is a ceremonial sword, but it is in fact a sturdy weapon. It stands up well against clashes with an opponent's weapon, but unfortunately, it is poorly balanced which makes it difficult to maintain an effective stance in battle.
