We’re not sure who the chef is behind this video, but he’s got some serious knife skills. Our jaws dropped when we saw the amazing lattice that emerged after he made a series of partial cuts through a slice of potato. Sure, the video has been sped up, but his precision is still on point.
This motorized rotary tool is better than scissors, especially when it comes to cutting materials like plastics, leather, carpeting, cardboard, and vinyl up to 1/4″ thick. It features a self-sharpening blade and ensures a clean, smooth cut in straight lines or curves. Aproca makes a custom-fit carrying case as an accessory.
There are lots of machines out there that can cut holes in flat sheets of steel, but MarkGyver built a machine that can make cuts into the curved face of a cylinder. Using a high-heat plasma cutter and a chain-driven rotating holder, the computer-controlled system can make smooth cuts through the surface of a steel tube.
We’ve always enjoyed watching videos of wood being turned on a lathe. However, the carving part is usually done with metal tools. The guys from the Waterjet Channel wanted to see if the powerful high-pressure cutting tip of their waterjet could be used to smoothly sculpt a spinning piece of wood in the same way.
If you’ve ever gotten a paper cut, you know how sharp the edge of a sheet of the stuff can actually be. The Q shows us how rapidly spinning a disc of paper on an angle grinder can turn it into a circular saw. Needless to say, keep all fingers and toes away from this thing.
