Saw 6 - Continue down the hall and turn to the right then possess the priest to get over the portal. Leave the priest, go outside and then return to the hall after the cutscene. Turn to the right and pass through the door into the rectory. Head to the end of the hall to find the sixth hand saw against some shelves on the right wall (Hand Saw 7).
