Toolmonger's got it right about this "Cabinet Jack":
It's refreshing to see a multi-tool that doesn't try to be all things to all people. Instead, the Cabinet Jack focuses specifically on cabinet making needs, assisting in tasks like cleaning up hinge mortises and ease edges.
I have a hard time sanding wood, let alone working it, but I get a kick out of seeing these sort of specialized tools.
