Concussion stick

Concussion sticks were chemical explosive weapons that could be easily disguised as data probes or similar items. Concussion sticks kept two chemical elements separate which were mixed when the concussion stick struck a solid object. Around fifteen seconds after activation, the stick detonated, generating a concussion blast. During the Galactic Civil War, Sessian Armaments produced the Concussion Stick Model 1-79.
