The multi-purpose tool consists of an ergonomically-shaped handle containing a series of keys (17, 18, 19) designed to open fire points, elevator and electricity control boxes, doors and windows with no handles, as well as opening blades (21) that can cut through safety belts and other materials, and fixed screwdriver blades. The pivoted ends of the keys are shaped so that they lock in the deployed position.
