How sharp is a piece of obsidian?

How sharp is a piece of obsidian?

It took 210 grams to cut the test media with the utility knife blade. That is quite sharp, but not as sharp as the obsidian….Obsidian Sharpness Results and Razor Blade Comparison.

Does obsidian have sharp edges?

Obsidian has been used across history to make weapons, implements, tools, ornaments, and mirrors. Because of its conchoidal fracture (smooth curved surfaces and sharp edges), the sharpest stone artifacts were fashioned from obsidian.

Can obsidian be sharper than diamond?

Surprising Things about 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.

Is obsidian the sharpest stone?

“The biggest advantage with obsidian is that it is the sharpest edge there is, it causes very little trauma to tissue, it heals faster, and more importantly, it heals with less scarring,” he said.

Is obsidian always sharp?

The high viscosity inhibits diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, brittle, and amorphous; it therefore fractures with sharp edges.

Is obsidian really sharp?

Obsidian is not particularly hard (unlike diamond), it’s just capable of being very sharp. Obsidian knives have however been used in medical procedures where very precise cutting is required and where laser surgery is not available.

What’s the 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.

How strong is obsidian?

Obsidian is rated at 5 to 5.5 on the Mohs scale of mineral hardness, with diamond rated at 10, and talc rated at 1. It has very high tensile strength, but is also very brittle due to low compressive strength. These characteristics have made it an ideal material for tool making for over 700000 years.

Is obsidian sharper than a razor?

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. 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.
