Kaladanda Staff is associated with Yama, the Hindu God Death. Yamraj carries the Kaladanda stick. It is a lethal and ferocious stick. Sometimes it is referred as club or Gada.
Yama got Kaladanda as a blessing from Brahma, the lord of creation.
It is the ultimate weapon and nothing can stop it. No boon can protect a living being from it. Once it the Kaladanda is thrown it will kill the intended living being.
Brahma gave the weapon to Yama to keep population in control and to punish those who follow Adharma.
