   Looks like you have a mortise gauge, a shame to trash the bar. Why not just make a new bar for it? Lee Valley sells a Japanese-style replacement blade you could design it around.

   Buy a cutting gauge. They really aren't that expensive. Or make your own using a #11 scalpel blade or Xacto blade.

   I have several. Very handy during a project to keep them set do various distances, such as when laying out tenon cheeks, haunches, offsets, etc.

   If I had to try to make it into a cutter, I'd mount the cutter on the very top. You would have to drill two holes. One for a dowel and the other for mounting the cutter. The dowel provides the screw that fastens the cutter will cross grained wood to hold it secure because end grain alone will not work. The dowel gets put in place before drilling the pilot hole for the screw. A washer goes under the cutter so that you can tighten down screw securely. I would rather make one from scrap wood and convert the one you've got into a mortising gauge.
