There are a lot of steps to create exotic cutting boards.

Selecting and buying the wood.

Jointing the wood, the step you are viewing. Cutting the wood into the appropriate size. Gluing the section of wood together to form a larger board. Using the Planer to smooth and level the glued pieces of wood. Using a rounter to create the rounded corners. Then sanding, sanding, sanding. The finish is applied after the board is smooth.
