A home-made man from India made a strange-shaped key. Despite the original design, the device can very well be used for its intended purpose.
Let's see how it works
The craft is created on the basis of an equilateral triangle made of a steel square. A nut is welded at each corner of the steel frame, with a thread directed to the center. To fasten the nut for loosening, long studs are used.
Using the craft is quite simple, the nut is placed in the center of the triangle and clamped with studs on three sides, after which the entire device must be rotated. The complexity of using this craft makes you think about the meaning of its creation, but you can think of a different purpose for the device.
