The Flicker is a type of sword and a sharp weapon, as well as an object capable of electrocution. The sword is part of Mutilate a Doll 2's Future Pack, with the four items in the pack (the other three being Twin Carbine, Twister, and Arc Grenade) designed by Veletronic.
The flicker can slice objects similarly to other sharp objects. Electricity is added into the flicker's blades, so the sword would electrocute any alive objects it touches. Rather than releasing yellow electric sparks, however, the flicker releases blue electric sparks.
