Metal, on the other hand, is worked and folded upon itself numerous times, depending on how it is processed. Don Crabtree produced obsidian blades for surgery and other purposes, and has written articles on the subject. The best scalpels actually have obsidian tips. One study found that obsidian incisions produced narrower scars, fewer inflammatory cells, and less granulation tissue in a group of rats. Even the sharpest metal knife has a jagged, irregular blade when viewed under a strong enough microscope when examined even under an electron microscope an obsidian blade is still smooth and even. Obsidian is hard and brittle it therefore fractures with very sharp edges, which had been used in the past in weapons, and are still used as surgical scalpel blades.Ĭurrent useObsidian has been used for blades in surgery, 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. The inhibition of atomic diffusion through this highly viscous and polymerized lava explains the lack of crystal growth. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silica content) induces a high viscosity and polymerization degree of the lava. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth.
They found that nuclear pasta is the strongest material in the universe, which makes it possible for neutron star crusts to have crustal mountains that are tens of centimeters high.Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. Tungsten What is the strongest material in the universe? Tungsten What is the strongest and sharpest metal? Steel scalpels tend to leave scars, even if temporarily. 4 MM thick, meaning it doesnt cut between the cells. Titanium, on the other hand, has a tensile strength of 63,000 psi. An obsidian blade is 3 nanometers thick, capable of cutting BETWEEN your cells, allowing for a much more painless surgery. But in terms of impact strength, tungsten is weak - it’s a brittle metal that’s known to shatter on impact. Tungsten vs Titanium In terms of tensile strength, tungsten is the strongest out of any natural metal (142,000 psi).
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.
The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. 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. 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.ĭamascus swords Can Obsidian cut through diamond?Ĭutting edge Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels.
