I am so stoked. I found this marking gauge on Patrick Leaches tool site and plunked down some cash. It is precisely as he described it. As is, it is a slitting gauge. It can cut the edges of a dado or rabbet. It has a removable tool steel cutter. I will be able to grind other cutters to cut beads or slots. very cool. Thank you Patrick Leach.
