The Sonic Screwdriver is a versatile tool and defensive weapon used by the Doctor. He can use it to hack devices and open doors (but it dosen't work on wood). Following his regeneration, the Doctor received a new Sonic screwdriver from the TARDIS. It differed radically from the previous model, having “claws” and a green diode, rather than blue. It also had copper plating in various places, similar to the new TARDIS interior.
Unlike it's brown and greeen show counterpart, this piece is completely gray, but it does have good detail.
