You have effectively overridden the biometric security measure on the Master's Laser Screwdriver. Your powerful laser weapon is ready for use. The Master's wicked tool. You won't find this screwdriver at your local hardware store! Just as the good Doctor has his trusty Sonic Screwdriver to get him out of any fix, the not-so-good Master uses the less subtle Laser Screwdriver, a fearsome device he employs mainly as a weapon to murder anyone who opposes him. Styled in faux chrome and brass, this credible replica looks just like the real thing… and it lights up and makes a buzzing sound.
