The invention relates to a device and method for making tenons using an adjustable shim placed between cutting blades. The adjustable shim has a plate with a recess capable of accepting spacers of varied thicknesses and a cover that encloses any of the spacers placed in the recess. The thickness of the adjustable shim is adjusted by placing spacers in the recess to shim apart the cutting blades leaving between them a distance approximately equal to the desired tenon thickness.
