The Screwdriver is an item in The Escapists. It is used to unscrew vents or chip walls.
Loses about 6.25% durability each time used on a vent. Lasts for up to 4 vents. It loses 10% durability when used to chip.
It can be bought from fellow inmates or obtained by beating up other inmates. The item is expensive though.
I think you can craft a Powered Screwdriver (Contraband) With Battery and Wire. It can also be crafted with a rope and some toothpaste.
