Can Obsidian be sharpened to a single atom?

While not quite as far as a single atom, knapped obsidian blades are a small and measurable number of molecules in thickness. And while diamond is the harder material, obsidian can be made sharper.

Can obsidian cut atoms?

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.

How sharp is volcanic glass?

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

How thick should the spine of a knife be?

The thickness of the spine depends on the height of the knife. For chef’s knives it can be 3.5 mm maximum and for carving knives ca. 1.5 to a maximum of 2 mm. The ‘Rosenbaum’ carving knife on the picture is much too thick.

Is Superman’s Sword sharp enough to cut electrons off an atom?

In Kingdom Come Wonder Woman has a magic sword that is sharp enough to “carve the electrons off an atom”. Leaving aside the ways that doesn’t actually make sense, it suggests a blade with an edge thinner than an atom. Superman accidentally cuts himself on the blade.

Why don’t atoms break apart when you cut something?

When you cut something neither the atoms break nor the molecules. This is because of high inter atomic and molecular forces present in between them. Only crystal structure breaks apart. Take salt, sand etc in bowl. Think salt as a complete solid. Atoms are attached to each other with help of atomic bonds. Thus atoms bond together to form molecules.

What makes Espada da Galáxia so special?

Brazilian novel Espada da Galáxia does it with an extra twist. Not just is the blade that names the book sharpened to a single atom, it’s also made of “metallic Hydrogen”, making its edge as thin as the smallest atom. In the Firebird Trilogy, the edges of crystaces’ blades are precisely one atom thick.

Can Hyperion’s katana cut a proton in two?

Hyperion’s sword, the Cataclysm Slash, can cut a proton in two. In this case, the sword was forged and given to him by a god. Mamoru’s katana from Until Death Do Us Part is a high tech monomolecular blade, able to break the bonds between molecules and cut anything (if the katana’s angled properly).
