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.

Is obsidian the sharpest material?

Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels. … “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.

Can obsidian be 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 is the sharpest stone?

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.

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.

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 razor?

Obsidian Sharpness Results and Razor Blade Comparison

Now for the exciting part. The results are in and the obsidian was almost twice as sharp as the brand new utility blade. It only took 134 grams of force to cut the test media vs. 210 grams to cut the media with the utility knife blade.

Can obsidian cut you?

Obsidian is not approved by FDA for use on humans because it is brittle and so it could leave fragments in the cut.

Is obsidian rare or common?

Obsidian is the most common form of natural glass and occurs in many attractive varieties.

Is obsidian a crystal?

It is chemically similar to granite and rhyolite, which also were originally molten. Because obsidian is not comprised of mineral crystals, technically obsidian is not a true “rock.” It is really a congealed liquid with minor amounts of microscopic mineral crystals and rock impurities.

What is sharpest knife in the world?

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).

Are Diamonds sharp?

Sharp but not strong. Diamond is the hardest on the hardness scale, but a regular steel even bronze would shatter it.

Is anything sharper than a razor?

Actually, the proven sharpest object is freshly broken chert or obsidian. The edge has been shown to be about one molecule thick.

Is obsidian as fragile as glass?

Obsidian breaks with a typical “conchoidal” fracture, like all glass and some other forms of natural rocks. Due to the near absence of mineral crystals in the glass, this smooth, curved form of fracture surface occurs.

What is the sharpest edge in the world?

Diamond blades are the sharpest blades because the molecular structure of diamond allows for an edge configuration that tapers down to as little as one atom thick.
