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 sharpest blade ever made?
The worlds sharpest sword is a Masamune Katana, although there are very few left in existence.

Is S110V better than S30V?
S110V is great steel and keep an edge quite longer than S30V. But may be more difficult to sharpen. I like S30V and S35VN though, it is very good steel for folder.
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.
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 sharp is black obsidian?
Obsidian (/əbˈsɪdiən/) is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock.
| Obsidian | |
|---|---|
| Color | Deep black or blackish green |
| Fracture | Conchoidal |
| Mohs scale hardness | 5–6 |
| Luster | Vitreous |
Is glass sharper 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 Chinese steel poor quality?
Low-quality steel is not structurally sound and has an increased potential to collapse or break. For example, in 2015 Chinese steel companies added the element Boron to their steel. However, the element Boron causes welds to crack. This is a terrifyingly huge safety hazard.
Is Obsidian the sharpest material on earth?
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.
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.
What knife does Gordon Ramsay use?

Are Diamonds sharp?
How sharp are diamonds? Yes as Diamond is the hardest substance in earth then yeah it is, It’s sharp edges and cuts are the reason it looks too beautiful as they help it to reflect more.
Can Obsidian cut through bone?
The thing with obsidian is that it is extremely brittle. Just get a 50-pound obsidian wedge, knap away the edge to make an axe and take a good whack at a bone. The edge will chip and crack for sure but that would probably be able to cleave a bone without breaking.
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.
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.
Can Obsidian be used to make a sword?
Obsidian can be used to make knives and other sharp tools, but it would not be suitable for a sword. For one thing, you won’t find a piece of obsidian long enough for a sword blade. Also, though obsidian is very sharp, it is also very brittle. Sure, obsidian melts (after all it flows when its lava).
Is Obsidian stronger than steel?
Obsidian is much, much harder than steel. At molecular width, it’s edge is hard enough to maintain that razor edge. At that thickness, the steel blade’s serration’s (the ones I mentioned earlier) are too weak, and will bend once you try to use that edge.
Can you make a diamond knife?
You could work pure diamond into something shaped like a knife, but it wouldn’t make a very good knife. Diamonds are hard, but they’re brittle.
Can Obsidian cut through DNA?
