             So, who cares.

    You do. It's very important to you for some reason. You said
    that blades go back half a million years, I pointed out that
    technically they go back millions and here you are *Still*
    arguing that a blade isn't a blade!  Clearly you care a lot.

    The important is, what those "blades" are doing. And it is obvious
    that those blades that emerged in the times that I mentioned, are
    working as sickles, because there is no reason to manufacture those
    things for some other reason.

    Cutting meat off the bone.

    Cutting an animal hide.

    With your short "blades" that you are mentioning, you can cut only one
    stem at the time.

    Apparently you're wrong.

    You can even use these little shards as deadly weapons:

    These are "microblades", which emerged only recently. But, this is all
    the same for you, of course.
    To cut hide you have to have solid sharp edge, not brittle long edge.
    You cannot use brittle stone in food preparation, because stone sherds
    will be left in food, so no meat cutting.

    Gee, you really don't get anything. Why you are in this group at all,
    if you don't even try to know something? What is "millions of years old"?
    BTW, those sickles resemble blades, instead of having multiple micro-blades, you can have one long blade. For those micro-blades to fit
    into this handle, you got to have a glue. So those sickles were possible
    only after you figure out how to make good glue, before that you only
    had the option of using a blade tool.

             To cut hide you have to have solid sharp edge,

    Flint is sharper than steel, obsidian is sharper than flint.

    They can cut an animal hide.

    Yes, exactly. So why would you need to make a blade? *Blade is long
    and narrow*. A toll is categorized as "blade" if it is twice as long as
    it is wide. So, blades are fragile, and they don't withstand strong forces.

    You're saying this because I pointed out that blades are known
    to have been in use for millions of years..

             BTW, those sickles resemble blades

    They're made up of a number of blades identical to those in use
    for millions of years. That's all. They just took a number of
    blades of a type produced for millions of years and set them
    in wood to create a sickle.

    instead of having multiple micro-blades, you can have one long blade.

    That is infinitely more difficult, working with flint or
    obsidian, than is using multiple blades (or a type produced
    for millions of years).

    Your main agenda on this news group is to talk about stone tools.
    Please, take *any* book about paleoanthropology or about stone tools,
    the simplest one, the basic, you don't have to read it all through, just
    read the basics, maybe only you have to read the titles, nothing more,
    please. Otherwise the discussion with you is completely senseless. You
    even don't know the basics, for god's sake. The basics. You have
    Wikipedia, for god's sake, that should be enough. But you don't read
    even that, and you have the courage to come here and talk BS. My god.
