What Is The Sharpest Material In The World?

Is there anything sharper than obsidian?

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..

Which sword is the sharpest?

Damascus swordsNanotech Used 2000 Years Ago to Make History’s Sharpest Swords. Damascus swords — sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling — owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.

Is Obsidian sharper than diamond?

Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts. … Obsidian is found all over the world.

Do surgeons use Obsidian?

Obsidian is used by some surgeons for scalpel blades, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels, the cutting edge of the blade being only about 3 nanometers thick. … Surgeons must be very careful to cut only soft tissues with the obsidian scalpel.

Why is obsidian so sharp?

Obsidian is always much sharper than steel, because of how it breaks. … When you break obsidian, it breaks in such a way that the edge can be a few atoms thick. When you break steel, it cannot break as cleanly as obsidian, leaving an irregular edge that is not as sharp as obsidian.

How common is Obsidian?

Occurrence of Obsidian Obsidian is found in many locations worldwide. It is confined to areas of geologically recent volcanic activity. Obsidian older than a few million years is rare because the glassy rock is rapidly destroyed or altered by weathering, heat, or other processes.

Is glass sharper than steel?

Modern glass knives were once the blade of choice for the ultra-thin sectioning required in transmission electron microscopy because they can be manufactured by hand and are sharper than softer metal blades because the crystalline structure of metals makes it impossible to obtain a continuous sharp edge.

Is it possible to melt Obsidian?

Obsidian can be melted if you can get it hot enough, but the problem is that what it is when it cools may not be obsidian.

Can Obsidian cut through cells?

Good quality obsidian fractures down to single molecules which can produce a cutting edge 500 times sharper than the sharpest steel scalpel blade (“American Medical News”, Nov. … On the cellular level an obsidian knife can cut between cells rather than tear the cells as a steel knife will do.

Is Obsidian the sharpest material?

Obsidian — a type of volcanic glass — can produce cutting edges many times finer than even the best steel scalpels. … When you consider that most household razor blades are 300 to 600 angstroms, obsidian can still cut it with the sharpest materials nanotechnology can produce.

Can Obsidian cut through steel?

No. Obsidian is relatively soft with a typical hardness of 5 to 5.5 on the mineral hardness scale. In comparison, quartz (crystallized silicon dioxide) has a hardness of 7.0. VERY TRICKY TO CUT STEEL WITH OBSIDIAN.

How strong is Obsidian?

Obsidian is relatively soft with a typical hardness of 5 to 5.5 on the mineral hardness scale. In comparison, quartz (crystallized silicon dioxide) has a hardness of 7.0. Obsidian occurs only where geologic processes create volcanoes and where the chemical composition of the magma is rich in silica.

Can Obsidian be used to make a sword?

Obsidian can be used to make knives and other sharp tools, but it would not be suitable for a sword. … Also, though obsidian is very sharp, it is also very brittle. One good hack or slash with an obsidian sword blade and it would probably shatter—like the glass that it is.
