An implant extractor tool including first and second pivotably connected arms having jaws at their distal ends adapted to engage an implant. The tool further includes an adjustment mechanism having an adjuster and a biasing member biasing one of the first and second arms, and an actuator operatively engageable with the adjustment mechanism. The actuator is movable between a first position locking the adjustment mechanism in a fixed position and a second position spaced from the adjustment mechanism permitting movement of the adjustment mechanism relative to the actuator. The implant extraction tool can be operated using one hand to engage an implant to be extracted.
