The Tite-Mark Long Deluxe has a 9" rod but is otherwise the same as the Tite-Mark Deluxe. It comes with one marking blade, one reverse-bevel marking blade, one scoring blade, two single-bevel adjustable mortise blades, a set of fixed-width mortise blades (four sizes), and a set of extensions. If you are squaring up stock and laying out mortise and tenons on heavier pieces, then the Tite-Mark Long Deluxe is your best choice, especially if you are laying out double and triple mortise and tenons.
