I had a nice 3" thick slab of spalted maple that was begging for some good project. I also had knives coming in and my block is full. So I designed and fabricated this self-supporting magnetic knife rack. It has 27 magnets 0.120" from the front surface in three rows to hold the knives. The face is tipped back 7º and the cut-out for the handles is 0.6" deep. Finish is mineral oil and wax. I'm pretty happy with how it turned out.
