What is the sharpest object in the world?

The sharpest object in the world is believed to be a tungsten needle that has been sharpened to a single atom point. This needle, created by researchers at the National Institute for Nanotechnology in Canada, is so sharp that it can puncture individual cells without causing further damage. It is estimated to be over 100 times sharper than a typical razor blade.

Sharpening an object to a single atom point is an impressive feat and demonstrates the precision that can be achieved with advanced nanotechnology techniques. The extreme sharpness of this needle opens up new possibilities for cutting-edge applications in areas such as medical research, nanotechnology, and material science.
