The Rodian cryogen whip was a close-range weapon manufactured by Sancretti Arms & Munitions, Interstellar which was favored in the underworld. Cryogen at a temperature of absolute zero flowed through the whip, making it extra painful on impact.
During the Clone Wars, a group of savage killers known as the Bartokk Assassins used a weapon that struck fear into everyone they faced. The Weapon was known as the Rodian Freeze whip and had a freezing cold liquid known as cryogen flowing through it. The cold chemical inside caused a horrific, near explosive reaction upon impact with any solid object and could break through most metals instantly. On top of that, it was capable of freezing metal and even bone in a single strike, leaving a target completely unable to move a limb if it was struck.
