I'm curious about using the tool. How much dust does it kick up? With a drywall saw I can (somewhat) control the dust. The particles are relatively large and by controlling the saw stroke, I can guide the bulk of the trash inside the wall with the remainder falling straight down. Airborne dust is minimal. I have tried using a powered saw, but airborne dust is significant. Further, I'm not likely to "feel" a wire behind the wall if I use a motorized saw. This tool is likely to throw dust every which way, but since there is no need for the blade to travel beyond the rear face of the drywall, wire damage is not likely.
