The Loag Dagger was a black blade which served as the emblem for the Loag assassins of Merisee. The ancient dagger had passed through countless hands since its seizure by Jedi Knights millennia ago. It was found to be missing from the Galactic Museum on Coruscant circa 11 ABY.

It was 30 centimeters long, with a one-sided curved black blade. It had a dark hide hilt and used a red ruby as a pommel cap.
