The sharpest knife in the world was introduced in 2006 in Chicago. American scientists have studied the edge of the blade under a multiple magnification microscope. The latest engineering developments were presented at the international mechanical engineering forum.
Incredible invention
The small thickness of the blade of the ultra-innovative tool was 10 -9 meters. 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, a tungsten filament can cut only soft materials. But scientists are working in this direction. The sharpest knife in the world was made using unique technology. Each element of the blade consists of tungsten atoms, which are filled with nitrogen.
The thickness of the bonding layer turned out to be equal to one atom. This achieves an incredibly sharp blade. The implementation of work on the production of tools is inexpensive, but the complexity of the process does not allow to start the mass production of knives.
Does the invention have a future and what are its advantages?
The sharpest knife in the world has undoubted advantages:
- They can even cut microorganisms for study.
- They can perform operations at the cellular level.
An indispensable tool in industry: in the production of medical devices, military technology, high-quality electronics. It is applicable wherever the highest accuracy of the cut is required.
The trace from the knife is not more than 50 microns. This tool can be cut along the thinnest human hair. Manufacturers note the resistance of the invention to high temperatures. It can be used at 800 degrees Celsius.
An invention for everyday life?
Kramer Knives recently introduced the world's sharpest kitchen knife for sale. Incredibly small blade thickness is achieved due to specially developed technology:
- 6,000 layers of steel from America, Japan and Germany are melted.
- A knife is made at a temperature of 1300 degrees Celsius.
- There is an incandescent stage in saline.
- Hand forging of each product.
Damascus steel knife has become the best among analogues. The blade is sharpened so sharply that the cut layers of the products are completely transparent. Professional chefs choose Kramer Knives, work in the kitchen turns into pleasure.
When ordering, the cost of a knife varies from hundreds to several thousand dollars. In the manufacturing process, each product acquires a unique pattern on the blade.
