What metal gets sharpest?

The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. It was manufactured by placing a narrow tungsten wire in an atmosphere of nitrogen and exposing it to a strong electric field in a device called a field ion microscope.

What material can be made the sharpest?

Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel blade has a saw like edge.

What is the sharpest blade on earth?

Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 times sharper than a razor blade. These are made by flaking a long, thin sliver from a core of obsidian (volcanic glass).

What is the strongest and sharpest metal?

Tungsten

Can tungsten stop a bullet?

The question is, Can a tungsten armor plate effectively protect you against bullets? The simple answer is yes. But we are talking about tungsten alloys however because tungsten itself has the highest melting point of any metal and for that reason would be every difficult to work with in mass production quantities.
