Shikra blade
From The Stargate Omnipedia
Weapon used by the Goa'uld Baal. The shikra blade is a short sword, light and easy to wield, with a thin blade approximately one meter in length. The blade is impossibly sharp, its edge is honed to the thickness of a single atom.
In an alternate timeline Baal wore the weapon in a sheath on his hip, and used it for executing his enemies up-close and personal.
