Obsidian has been used as a cutting tool since the Stone Age, but modern versions of obsidian scalpels are manufactured by a Virginia archaeologist using a pressure flaking process. Each knife can be used from 10 to 20 times before being discarded, Green says.
Do surgeons use obsidian scalpels?
Even today, a small number of surgeons are using an ancient technology to carry out fine incisions that they say heal with minimal scarring. Dr. Lee Green, professor and chairman of the Department of Family Medicine at the University of Alberta, says he routinely uses obsidian blades.
Do they use obsidian in surgery?
Why is obsidian used in cardiac surgery? Obsidian is used in cardiac surgery, as well-crafted obsidian blades have a cutting edge up to five times sharper than high-quality steel surgical scalpels, with the edge of the blade reaching veritable molecular thinness.
Whats stronger obsidian or 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 is the sharpest blade ever made?
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 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.
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.
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.
How much money is Obsidian?
There is no set value or market for obsidian, unlike silver and gold, where there are world markets and indices. Obsidian is not an expensive stone. This being the case, a piece of obsidian can cost $2 or $100 depending on the quality and processing it has undergone, you can shop at Amazon.
Is Obsidian rare?
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.
What is world’s sharpest knife?
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 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.
What are obsidian scalpels used for?
Obsidian is a type of volcanic glass that produces a much finer blade than conventional steel. It is ideal for applications where an extremely fine cutting action is required or where trace metals from ordinary scalpel blades cannot be tolerated.
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. 2, 1984:21). On the cellular level an obsidian knife can cut between cells rather than tear the cells as a steel knife will do.
Are diamonds used to cut diamonds?
Diamond manufacturers cut a groove in the diamond with a laser or saw, and then split the diamond with a steel blade. Sawing is the use of a diamond saw or laser to cut the diamond rough into separate pieces. This step gives diamonds their initial shape.
Is Obsidian sharper than metal?
How much sharper is obsidian 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.
Why is obsidian so smooth?
Obsidian is quite unique due to its smooth, uniform volcanic glass texture. Obsidian is usually considered an extrusive rock, because it usually solidifies above Earth’s surface where the edges of a lava flow come into contact with cool air or water. Geologists call the way obsidian breaks a conchoidal fracture.
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.
Is Obsidian stronger than diamond in real life?
Is Obsidian sharper than diamond? 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.
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.
Can Obsidian cut through 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.
What’s tougher than a diamond?
Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond. Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.

|---|---|
| Color | Deep black or blackish green |
