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.
Is Obsidian sharper than a razor?
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.
Is there anything sharper than obsidian?
Obsidian is volcanic glass and CAN be made sharper than what is possible with steel, but many mistake this fact with a myth that obsidian knives will ALWAYS be sharper than steel. The obsidian blades you can buy in the under $100.00 range will not likely be sharper than steel.
Can Obsidian cut your DNA?
Can Obsidian cut through DNA? TIL Obsidian Blades are so sharp that they can cut cells and DNA. They are used are used in modern medicine because the sharp blades create incisions which heal faster.
Why is obsidian so sharp?
Obsidian can be so sharp due to it’s hard, glass-like characteristics. It’s brittle qualities are a side effect of this hardness. Unlike metal knives, obsidian blades are never used to pry with. Obsidian is volcanic glass and just like regular glass it can be very sharp and very brittle.
Is ceramic sharper than glass?
The sharpest edge known to science is freshly broken glass. Ceramics are muti-crystalline; the size of the crystallites limits the sharpness of a ceramic blade. But glass is has no crystals, it is homogeneous so the edge can be atomically sharp.
Can you make things out of obsidian?
Obsidian was used to make knives, arrowheads, spear points, scrapers, and many other weapons and tools. Once these discoveries were made, obsidian quickly became the raw material of preference for producing almost any sharp object.
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.
What is the sharpest stone?
Obsidian, which is a naturally occurring volcanic glass, is known to be one of the sharpest materials found in nature. It is formed as an extrusive igneous rock and was used in the past in cutting and piercing tools. Interestingly, Stone Age blades are still used for cutting in modern surgery.
What can obsidian cut?
Even with centuries of metallurgic knowledge, an obsidian blade can be still be hewn 500 times sharper than steel. In fact as seen under a microscope, an obsidian scalpel will cut cells neatly in half where the finest steel scalpels will look as if they had cut through cells with a chainsaw.
What is the sharpest sword in history?
What was the sharpest sword ever made? Nanotech 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 is the sharpest pocket knife in the world?
Kershaw Blur Black 1670BLK Everyday Carry Pocketknife If you are looking for the sharpest pocket knife in the world, you can definitely find one here.
Is Obsidian a good weapon?
Natural obsidian is a pretty terrible substance to make a durable weapon with, but there are other “obsidian like” materials that could work. “Obsidian like” being glass with impurities “It’s not the strongest material ever made, but it’s certainly one of the best with a combination of strength and toughness.”Mar 18, 2017
What has the sharpest edge?
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.
Do doctors 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.
What is the most sharpest thing on earth?
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 Obsidian fragile?
Obsidian is quite a fragile stone, rating a 5.5 on Moh’s hardness scale. It can be easily chipped or broken on impact.
Is Obsidian real?
Obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite.
Is Obsidian sharper than glass?
Obsidian has a Moh’s hardness of 5 to 5.5 while regular (non-volcanic) glass is 5.5. Because of its rather unique molecular structure, it can be cut or fractured to form blades that are sharper than surgical steel and by far sharper than glass.
Can Obsidian be made stronger?
Is Obsidian stronger than steel? Steel can be honed to make that cutting edge thinner, and thus, sharper. Steel can theoretically be honed until its edge is just a single molecule wide like obsidian, but here the limitations of the metal come in to play. Obsidian is much, much harder than steel.
Can you melt Obsidian?
Melting yes, casting it no. Obsidian is an amorphorous substance that is to say it is glass with a completely random internal makeup. Quenching would also have to take place, so its likely you would have to handle it like glass blowers blow their glass.
How strong is Obsidian?
| Obsidian | |
|---|---|
| Color | Deep black or blackish green |
| Fracture | Conchoidal |
| Mohs scale hardness | 5–6 |
| Luster | Vitreous |
