Half-blind mitered dovetails combine the visual effect of a miter joint, with continuous grain wrapping around a corner, with the strength and classic look of dovetails. The hardest part is creating a perfectly true mitered shoulder surface between pins. But Michael Fortune's router jig makes the process more straightforward by holding the workpiece at 45° so the pins can be routed with a straight bit for parallel cheeks, then angled by hand using a trim saw and chisel.
