The deep groove pattern is a simple, more Shaker style pattern.  The cut away in the front gives a better idea of the depth of each of the areas of the cut. We have four different cutter sizes, so the blocks look proportional in all of the many sizes of blocks that we can make.  
If you are trying to match some blocks you already have.  
Our cutter sizes are: 2 1/8″, 2 5/8″, 3 1/4″ & 3 3/4″ in diameter.
