Abstract
A tool that can be held and operated with one hand to attach a corner bead to an outside corner of drywall includes a substantially V-shaped member having a pair of interior surfaces disposed at an angle of less than 100° and a frame or handle attached thereto. The handle may be sized and shaped to fit comfortably in the palm of a human hand. A pair of opposed pincers having pointed tips are pivotally mounted relative to the V-shaped member so as to allow the tips to move in a converging direction. A mechanical linkage system translates force applied to the handle into a converging motion of the pincers.

An apparatus for enabling single-handed attachment of corner beads comprising:
- a frame;
- a pair of contact surfaces rigidly coupled to the frame;
- a handle pivotally attached to the frame;
- a pair of pincers pivotally connected to the frame;
- a mechanism for biasing the handle into a biased first position comprising a spring extending between and coupled to each of the a pair of pincers;
- and
- a linkage mechanism operably coupling the handle to the pair of pincers for translating a force displacing the handle in a first plane into a controlled converging motion of the pincers in a second plane substantially perpendicular to the first plane.
