A wakizashi is a Japanese sword best known for being used by samurais.

Grauq owned a 23rd century wakizashi, as well as a katana. Iliana Ghemor took Grauq's wakizashi from the Otamawan before she destroyed Grauq's ship, killing Grauq himself.

Ghemor later used Grauq's weapons against Savonigar. Using the wakizashi, Ghemor managed to slash through Savonigar's body armor and injured his abdomen. Ghemor lost the weapon when the Nausicaan threw her against a boulder. (DS9 novel: Warpath)
