Certainly you can use spin saws for cutting straight lines though I have never personally used one but for the sort of crisp line Carl is looking for he will want a very good straight edge well clamped down and square to the edge. A circular saw is probably the better tool and, depending on the thickness I sometimes like to use a good straight edge router bit. This eliminates chipping altogether.
Traditionally one would use a hand saw to cut close then finish with a quality block plane to a scribed line. If you don't have a power saw this would be my suggestion. They do make planes with a fitting on one edge to help you keep it at right angles to the face of the board as you plane. To reduce or defeat tear-out at the end of the plane stroke cut a slight slope at the end.
