What’s the sharpest thing in the world?
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..

Is glass harder than diamond?
The diamond component is 800 times thinner than a Gorilla Glass 5 panel and stronger than a pane of sapphire glass. … Because diamond is harder, it won’t scratch, but it can shatter.
Are black diamonds worth anything?
In comparison to the rarer fancy colored diamonds, natural black diamonds are relatively affordable, and comparable in price to colorless diamonds. A fancy black diamond will cost anywhere in the region of $3000 to $5000 per carat. This would mean your average 1 carat wedding ring is likely to cost $3000.
Is gold heavier than diamond?
gold has a specific gravity of 19.32. So diamond is not nearly as heavy as lead or gold.
Can Obsidian cut through DNA?
They are used are used in modern medicine because the sharp blades create incisions which heal faster. Uncoiled, human DNA from a single cell is about 6 feet long.
What is the sharpest part of the body?
elbowThe elbow is the hardest and sharpest point on the human body.
Is Obsidian sharper than steel?
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 can break a diamond?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. A diamond is made entirely of carbon atoms which are joined in a lattice-type structure.
Are Diamonds bulletproof?
A diamond is one of the hardest known substances. … A bullet can easily shatter a diamond. A bullet would have more trouble shattering your arm than a diamond (unless it was a very big diamond. Then it might stop a bullet.
Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
Is Diamond sharper than obsidian?
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.
Can I crush a diamond with a hammer?
yes, diamond can be broken easily by the hammer. look diamond is strong when it comes to its structure and bond, but when with sure force and specific point it has been hit, it will be broken.
Is there anything stronger than diamond?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Can a hammer destroy a diamond?
Diamonds are one of the hardest gems, making them hard to cut, but they’re very fragile! This makes them quite easy to smash (not easy enough where you can drop it or throw it) with a hammer or dropping an anvil on it. … Steel and other rocks can be used to easily crush a diamond.
Do surgeons use Obsidian?
Cutting edge 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. Even today, a small number of surgeons are using an ancient technology to carry out fine incisions that they say heal with minimal scarring.
What was the sharpest sword ever made?
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.
What material makes the sharpest knife?
Carbon steel bladesCarbon steel blades are among the sharpest blades available and are much easier to sharpen than stainless steel blades. The lack of chromium in the blades means that it is highly susceptible to rust and corrosion and requires careful cleaning after each use.
