Have you ever needed to cut a square or rectangular hole into drywall? Such as you might need if you needed to install the electrical box for a light switch?
For most people, that's something that would take drilling at least two round holes at the opposite corners of the square or rectangle you intend to cut, large enough to insert the blade of a saw, which you would then proceed to use very carefully and very slowly to cut out a square or rectangular plug from the drywall. When you're done cutting the hole, in addition to a hole in your wall in the rough shape of a square or rectangle and a drywall plug that you might have accidentally dropped into the wall, you might also have tears or broken drywall to repair in addition to a coating of gypsum dust to clean up from yourself, the wall and the floor.
Wouldn't it be cool if you could have just cut a perfectly square or rectangular hole in the wall to do the job more efficiently, more effectively and, let's be honest, better?
The future has gotten to be a lot cooler than it used to be! And by future, we mean 2017:
The QuadSaw was patented and developed by Genius IP and is set for release in the UK in the summer of 2017. The company is said to have models sized for the electrical boxes used in the US. The tool is expected to sell for £199 (about $220 USD). That's a lot to spend for a hole cutting attachment but could be worth it to the electrician who regularly installs old work (retrofit) boxes in drywall.
Just in case you're looking for ideas of what to get such a person for their birthday or for Christmas next year!
