Well-crafted obsidian blades, like any glass knife, can have a cutting edge many times sharper than high-quality steel surgical scalpels: the cutting edge of the blade is only about 3 nanometers thick.
Is Obsidian 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.
Do surgeons use Obsidian?
Obsidian is used by some surgeons for scalpel blades, 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.
Is Obsidian better than steel?
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.
Why is Obsidian no longer used in surgery?
In fact, it is suggested that because obsidian scalpels are so perfectly smooth (it is only 30 angstroms thick as well), they may reduce inflammation and the wounds they generate may heal faster.  Some physicians are a fan, however they are not FDA approved and obsidian can also be very brittle.
What can break Obsidian?
Obsidian is the hardest material in Minecraft. It can be collected only with a DIAMOND PICKAXE.Sadly it takes roughly 10 seconds to mine out. Any other pickaxe will simply break the block after about a minute of mining. Obsidian is created when a source Lava block comes in contact with a flowing Water block.
Does obsidian chip easily?
The conchoidal fracture of obsidian causes it to break into pieces with curved surfaces. This type of fracturing can produce rock fragments with very sharp edges. The easy-to-recognize rock became one of the first targets of organized “mining.”
