Abstract: The seamsaver is a recess creating device available in one of three embodiments. Each embodiment is designed to prevent the potential ridging and crowning of butt joint seams in different situations. The first embodiment comprises a rectangular panel with a single elongate ridge attached on the front face, vertically centered and horizontally to one side. A second embodiment is identical to the first except that it has an additional ridge attached on the same face but opposite side. The ridge may be formed by an elongate rectangular block, a channel, or an angle, the channel and the angle having a wedge-shaped flange attached to the front face of the rectangular panel. The third embodiment has no ridges but comprises an elongated rectangular block of wood with a uniform, elongated dip running length-wise which is used to create an elongated recess running along the seam instead of across the seam.
