Abstract: An improved wood patch, in combination with a slot formed in a blemished wooden surface, and apparatus and method of manufacture thereof. The improved wood patch has, where the wooden surface to be repaired is horizontal, three faces: a flat horizontal exterior face, a flat vertical interior face, and an angled arcuate interior face. The patch has both a larger vertical radius of curvature and a larger angle between the flat vertical interior face and the angled arcuate interior face than the slot. Apparatus for manufacture includes a router utilizing a double router bit having a straight cutting edge oriented perpendicular to the axis of rotation of the bit and an angled cutting edge oriented at an angle to the straight cutting edge.
