Description of what it was made for:
"This is a saw for a depth controlled cut of plastic, specifically for
cutting open a "wall wart" without damaging the transformer inside. I needed
to resolder the output wires after they broke at the edge of the box. I put
this in the chuck of a drill press, turned it on, then moved the transformer
box around to cut it open along the existing seam."
