Abstract:
A hand tool is provided for the application of joint compound on wall board, having a planar blade affixed to an ergonomic handle. The blade has a concave arcuate working edge, wherein the concave arcuate curve extends the entire length of the working edge to each corner of the working edge. The concave arcuate working edge may be used to apply a self-feathered layer joint compound over drywall tape on planar butt joint or an inside corner joint. The blade is laterally flexible.

Claim (Index 5):
A method for applying joint compound to an inside corner joint between two drywall board surfaces, wherein the surfaces are in an approximately perpendicular orientation between the two surfaces, comprising\n a. applying a layer of joint compound to each corner surface of the corner joint, a layer of tape to each surface aligned with the corner, and a second layer of joint compound over the tape, b. pulling the tool of  claim 1  along the axis of the edge so a proximal corner of the working edge of the tool abuts the approximately perpendicular wall board surface and the distal corner of the working edge in is contact with the wall surface, c. wherein the pulling of the tool is crabbed slightly by keeping the distal corner of the working edge slightly behind the proximal corner of the working edge such that the proximal edge of the blade is not in direct contact with the other approximately perpendicular surface of the inside corner; d. wherein the pulling of the tool forms an angle defined by a surface of the wall, the corners of the working edge of the tool, and the plane of the blade, to spread and self-feather the layer of joint compound over the corner bead; e. wherein the self-feathered joint can be directly painted over to give a smooth wall, and f. wherein steps b-d are repeated for the other side of the corner.
