The sharpest knife in the world was presented in 2006year in Chicago. American scientists have studied the edge of the blade under a multiple magnification microscope. At the international engineering and mechanical forum, the latest developments of science were presented.
Incredible invention
The small thickness of the blade of the ultra-innovative tool was 10-9 meter. The sharpest knife in the world was intended for cutting small parts for microelectronics. It looks like a needle, the material for which is tungsten.
However, the tungsten filament can only be cutsoft materials. But scientists work in this direction. The world's sharpest knife was made using a unique technology. Each element of the blade consists of tungsten atoms, which are filled with nitrogen.
The thickness of the fastening layer was equal toone atom. This achieves an incredibly sharp blade. The execution of work on the production of the instrument is low-cost, but the laboriousness of the process does not allow the mass production of knives.
Is the future of the invention and what are its advantages?
The sharpest knife in the world has undoubted advantages:
- They can cut even microorganisms for study.
- They can carry out operations at the cellular level.
Indispensable tool in industry: in the manufacture of medical devices, military technology, high-quality electronics. It is applicable wherever the highest cut accuracy is required.
The trace from the knife is not more than 50 microns.This tool can be cut along the thinnest human hair. Manufacturers point out the resistance of the invention to high temperatures. It can be used at 800 degrees Celsius.
An invention for everyday life?
Recently, Kramer Knives has introduced the world's sharpest kitchen knife for sale. Incredibly small thickness of the blade is achieved due to a specially developed technology:
- 6,000 layers of steel are melted from America, Japan and Germany.
- Make a knife at a temperature of 1300 degrees Celsius.
- There is a stage of incandescence in saline solution.
- Hand forging of each product.
The knife from damask steel became the best among analogues.The blade is sharpened so sharply that the cut strata of the products are absolutely transparent. Professional chefs choose Kramer Knives, working in the kitchen turns into pleasure.
When ordering, the cost of a knife varies from hundreds to several thousand dollars. During the manufacturing process, each product acquires a unique pattern on the blade.
