Obsidian is much, much harder than steel. At molecular width, it’s edge is hard enough to maintain that razor edge. If you look at obsidian’s edge under a microscope, it is a perfectly smooth, sharp line. Steel (sharpened to a razor edge) will look like a toothed saw blade.
How strong is obsidian compared to 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.
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 Steel holds the sharpest edge?
Tempered steel makes the sharpest blades. However blades of laminated steel with carbide in the middle hold their edge longer, but the tingsten is brittle, and prying on anything can cause it to chip.
Is Obsidian durable?
The use of obsidian in jewelry can be limited by its durability. It has a hardness of about 5.5 which makes it easy to scratch. It also lacks toughness and is easily broken or chipped upon impact. These durability concerns make obsidian an inappropriate stone for rings and bracelets.
What is the sharpest natural thing in the world?
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.
What can break Obsidian?
The only one thing that can break obsidian is diamond pickaxe and netherite pickaxe.
What is the strongest rock in the world?
The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is technically the strongest rock in the world.
Can Obsidian cut through bone?
The thing with obsidian is that it is extremely brittle. It’s basically glass. So even though it can be insanely sharp when the edge is first produced, the edge quickly dulls and chips away. Just get a 50-pound obsidian wedge, knap away the edge to make an axe and take a good whack at a bone.
What is the sharpest metal in the world?
In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it’s a brittle metal that’s known to shatter on impact. Titanium, on the other hand, has a tensile strength of 63,000 psi.
Is Obsidian worth anything?
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.
Can Obsidian cut through diamond?
Cutting edge Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.
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.
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
How strong is obsidian steel?
Obsidian fractures conchoidally down to the very last molecule, so essentially when you break a piece off the very edge is only a molecule thick. It is at least 50 times sharper than surgical steel can get, and I’ve heard some say as much as 500 times sharper.
What is the 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 the weakest rock?
Sedimentary rocks tend to be the ‘weakest’ of the three, as Igneous and Metamorphic rocks both undergo extreme pressures to form.
Can a sword be made out of obsidian?
Its sides are embedded with prismatic blades traditionally made from obsidian. Obsidian is capable of producing an edge sharper than high quality steel razor blades. The macuahuitl was a standard close combat weapon. Use of the macuahuitl as a weapon is attested from the first millennium CE.
What is the softest rock on Earth?
The name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.
What is stronger 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.
Can Obsidian cut your 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.
