A Wooden vs iron sword causing bone fracture

  1. May 6, 2017 #1
    I'm trying to talk science to anthropologists and hope an academic physicist will let me quote him. Here is the data and my purpose is to prove that wood can't slice a skull the way a sword does . good grief .....
    " On this basis, the boomerang is the most probable candidate for the main trauma. , ..Of the weapons tested, the frontal wound observed in Kaakutja most closely resembles that produced by an African ‘Samburu’ sword".

    An iron boomerang will not work.

    Aluminium and lightweight carbon based structures (wood) work though,
    I love Carbon, but so does everybody.
    The perfect way to decapitate somebody would probably need a sword constructed from depleted Uraniam

    Swedish svardet means "sword" , it became lightweight carbon but sank and stopped working. .
    "Svärdet was under the command of Claes Uggla, and fought in the Battle of Öland. Before the surrounding enemies could board Svärdet, a Dutch fireship accidentally set her ablaze. The fire eventually reached the gunpowder store, which set off an explosion that sank the ship. "
    Charcoal and iron sink. Uranium blades at mach6 are deadly.
