Q-Bert 3D cutting board process

There are 3 types of cutting boards: end-grain, edge grain and face/flat grain.  All three types of grain are present on any board.  This example uses 8” wide by 3/4” thick by 24” long boards.  On these boards the flat grain shows when you look down at the board lying flat on the 24”x8” side.  The edge grain shows when the board is standing on the 24“x¾” edge with the 8” side up.  The end grain shows when the board is standing on the 8”x¾”edge.  Each type of board is made.  Based on the amount of work required flat grain tend to be the least expensive, edge grain next and end grain the most expensive.
