A clay cutting and beveling tool (100, 300) includes a guide ruler (115) including a guiding edge (410) and a cutting guide (120) in sliding engagement with the guiding edge. The cutting guide includes a body (520) formed with a plurality of angled through holes (530) each passing through the body at a different angle. The tool (100) is placed onto a clay slab (105) with a support surface (445) in contact with a top surface of the clay slab. A pin tool (110) is inserted into one of the angled through holes and left in engagement with the angled through hole as the cutting guide is advanced along the guiding edge. The pin tool cuts the clay slab with a beveled cut. A non-beveled through hole (535) also passes through the body (520) and is used to make non-beveled cuts.
