Sap

World of Darkness - Armory
The sap is usually a palm-sized flat “bag” of leather filled with lead shot or powder. For a small weapon, though, it packs a big wallop.
The sap used to be part of every cop’s arsenal about 20 years ago. After a quick hit from the sap, a criminal would think twice about acting violent. When used, the bag of shot — often targeted at elbows, knees, collarbones or even noses — did such sudden trauma to the target that it would leave him or her stunned, howling in pain.
Using a sap can causes a Stun effect. Unlike other Stun weapons, if the damage caused by the attack meets or exceeds the target’s Stamina (not Size), the target loses his next action.
