What type of blade holds the best edge?
The steel with the highest slicing edge retention has the maximum amount of vanadium carbide and it is heat treated to a high hardness. Therefore among available knife steels we would expect a steel like 15V or Rex 121 to have the best slicing edge retention because of the high MC carbide volume.
What material can hold the sharpest edge?
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.
What is the strongest and sharpest material on earth?
Diamond is the hardest substance found on earth in so many natural forms, and it is an allotrope of carbon. The hardness of diamond is the highest level of Mohs hardness – grade 10. Its microhardness is 10000kg/mm2, which is 1,000 times higher than quartz and 150 times higher than corundum.

Due to a difference in forging techniques, Japanese steel blades contain much more carbon than German blades, making them harder, but also more brittle. Because Western-style steel is relatively softer, it’s capable of holding an edge longer and doesn’t need to be sharpened quite as often as Japanese blades do.
Is obsidian sharper than a scalpel?
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 centimetre — an obsidian scalpel can equal diamond in the fineness of its edge.
Is there anything sharper than obsidian?
Short answer: No. Long answer: obsidian is a very hard and brittle material. This means that it will break easily, but can also be made extremely sharp. In fact, obsidian arrowheads and knives are some of the sharpest in the world.
