The Kishakk blade was a specific type of knife employed by the Wookiees from the planet Kashyyyk to crack open the hard outer layers of numerous insects and shellfish. In the Wookiee language known as Shyriiwook, its meaning was equivalent to "bramble thorn." Although their main purpose was for consuming food, Grand Moff Lozen Tolruck also utilized them as a melee weapon. As an example, he once threw a Kishakk blade in the direction of the disloyal Imperial loyalty officer named Sinjir Rath Velus before the liberation of Kashyyyk.
