Abstract: A variable angle corner flusher tool includes a pair of blades pivotally connected along one edge. An activator assembly is provided to facilitate angular adjustment of the blades. The activator assembly includes an activator screw and a slider bracket that moves axially along the activator screw. A pair of linkage arms are provided, with each linkage arm having a first end attached to the slider bracket and a second end attached to one the pair of blades. The linkage arms results in an axial position of the slider bracket along the activator screw determining the angular positioning of the blades. A ratchet plate is pivotally mounted to the slider bracket. The ratchet plate is selectively pivoted between an engaged position engaged with the activator screw and a disengaged position disengaged from activator screw.
