Abstract: Paint brush edge guide tool for a brush handle, has a proximal attachment, a stabilization plate disposed adjacent the handle, and a first elevated plate rising above the stabilization plate. The elevated plate rises at an acute angle away from the 3-D brush plane, being twisted about an axial centerline of the plane. An elevated terminal plate extends beyond the first elevated plate and is twisted about the centerline. The terminal plate distal edge extends beyond the terminal edge of the 3-D brush plane and the terminal plate is disposed at an obtuse angle from the elevated plate such that the terminal plate edge extends longitudinally beyond the 3-D brush plane and lies substantially adjacent the facing region of the 3-D brush plane. The terminal plate is twisted about the centerline. The interface between the elevate plate and the terminal plate may be a flex joint.
