ABSTRACT:
The present disclosure describes drywall tools that employ rotatable joints, e.g., ball joints, and methods of using such tools. One particular implementation of a drywall tool includes a body having a recess adapted to pivotably receive a rounded connector of a handle. A retainer carried by the body includes first and second rods. Each of the rods is rotatable about an axis and has a non-uniform circumference with respect to that axis such that such that a surface of the rod is spaced farther from a recess axis of the recess when in its open position than when in its closed position.
