The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.

A tool. A firearm, a blade and an ancillary device are disposed within or on the tool. The firearm comprises a barrel through which a bullet passes to exit the firearm, a firing pin moveable to a firing position by operation of a firing pin control, a firing pin lock retaining the firing pin in the firing position when in the locked position, a biasing member for applying a force to the firing pin with the firing pin restrained against the force by the locked position of the firing pin lock. A trigger releases the firing pin lock from the locked position, such that the force causes the firing pin to strike the charge proximate the bullet. The bullet then exits the barrel.
