The arakh is the standard weapon used by Dothraki warriors. It is a long blade, making a semi-circular curve in its lower half, making it half-sword and half-scythe.
Jorah Mormont notes that while the sweeping blade is effective and indeed necessary for a warrior on horseback, the arakh pales in comparison to the sword for battling without a mount or at penetrating armor.
In the booksEdit
The arakh is similarly described in the books.According to the TV series official pronunciation guide developed for the cast and crew, "Arakh" is pronounced "Ah-rock", as opposed to "Ah-RACK".
