There are few tasks more infuriating than trying to remove rust from just about anything. That's exactly why this laser is pretty much the best tool I've ever seen.
This amazing device is called the P-Laser QF-1000. Like its much larger counterparts, the 1,000-watt handheld tool is meant for industrial applications, like preparing metal for robotic welding or removing residue from manufacturing molds. However, it also does an excellent job when it comes to making rust disappear right before your very eyes.
Just watch this mesmerizing video of the laser in action.
I could stare at this all day, honestly.
But if you're thinking about getting one of these for yourself, know that it'll cost you a cool $50,000. I'll pass.
