Abstract: A wrench assembly includes first and second wrench members, and a switch, having an engagement member and a proximal extremity, mounted to the first wrench member. The switch moves between engaging and disengaging positions of the engagement member. The proximal extremity is undepressed in the engagement member engaging position, and is depressed in the engagement member disengaging position. The switch moves from the engagement member engaging position to the engagement member disengaging position, when the second wrench member is partially installed into the first wrench member. The switch moves from the engagement member disengaging position to the engagement member engaging position releasably engaging the engagement member to the complemental engagement member disabling the second wrench member from being withdrawn from the first wrench member, when the engagement member registers with the complemental engagement member when the second wrench member is installed into the first wrench member.

Abstract: A weaponized drinking vessel is an apparatus that contains a beverage and inflicts significant damage and pain against an attacker. The apparatus includes a holder body, a drinking vessel, a plurality of impact ridges, at least one light source, a microcontroller, and a power source. The holder body protects and further insulates the drinking vessel. The drinking vessel contains a beverage and insulates the beverage. The plurality of impact ridges increases the force and trauma of the apparatus against an attacker. The at least one light source illuminates the surrounding environment of the apparatus so that a user may accurately impact the plurality of impact ridges, as well as the holder body against an attacker. The microcontroller and the power source allow the at least one light source to operate. The apparatus further includes a lid that protects and contains the drinking vessel within the holder body.
