    A sword that cuts insect

    Did you hear rumours that in ancient times there were swords that could cut insect? I think this is interesting, because of the material it is made of. Could it be that it is made of stone, a metal oxide. As I know, a metal blade just can't be so sharp. So lets's imagine, it was a very cool stone sword with a beautiful handle. We are only approaching the stone age now, because metals are much easier to tame than stones (saphire, diamonds, countless concretes, countless granites, countless porcelain - they are more countless, than alloys). Also, it is interesting to know more about how plastic materials were used. Even in museums you can find things with plastic handles, such as sickles. Plastics are not very stable materials, so over a short time they degrade to a more stable form of hydrocarbons.

    It has long been known that many obsidian blades are sharper than steel blades although I don't know if they were used to cut insects

    I'm always still in trouble again

    And they're also deadly against White Walkers.

    Ancients could shave. Obviously, they had the ability to get a decent edge on a blade. Insects aren't that tough to cut.

    I've seen a bronze shaving razor in a museum a few years back. IIRC it was Egyptian and was somewhere around 2500 years old.

    Getting back to obsidian blades, as this snippet from a CNN article points out they can be quite a bit sharper than your typical steel blade

    Source: How Stone-Age blades are still cutting it in modern surgery


    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.

    When you consider that most household razor blades are 300-600 angstroms, obsidian can still cut it with the sharpest materials nano-technology can produce.

    Even today, a small number of surgeons are using an ancient technology to carry out fine incisions that they say heal with minimal scarring.

    I mean, that if an insect flies and meets the blade, it is cut, or the wings are damaged. Or if a piece of paper is falling down on a blade, it is cut by two.

    Sounds like some of the legends which surrounded Damascus steel

    You're talking about toys. Sure, an obsidian blade or a newly honed blade could be made to do that but neither can hold such an edge making them pointless in combat. The Japanese managed with steel much later but had largely abandoned shields by then. Not sure even a katana could handle constant bashing against flat steel but a bronze sword sure as heck can't against wood.

    I thought he was talking Bronze Age or earlier?
