Secret's out for Saracen sabres

DURING the middle ages, the Muslims who fought crusaders with swords of Damascus steel had an edge - a very high-tech one. Their sabres contained carbon nanotubes.
From about AD 900 to AD 1750, Damascus sabres were forged from Indian steel called wootz. Peter Paufler of the Technical University of Dresden, Germany, and colleagues studied samples of a 17th-century sword under an electron microscope and found clear evidence of carbon nanotubes and even nanowires.
The researchers think that the sophisticated process of forging and annealing the steel formed the nanotubes and the nanowires, and could explain the amazing mechanical properties of the swords (Nature, vol 444, p 286).

The rope will be in tension. Whether it breaks before a handle is pulled off the cabinet could be made a wager.
Now they add carbon a different way.
Damn, I missed that one. Not surprised at the results, though. Even the source I read seemed dubious, as I recall.
Japanese propaganda was just that: propaganda.
An interesting example of it, though, which harkens back to the pre-WW1 European belief that really good troops could advance against machine guns, which were better suited for gunning down native rabble in the colonies. The Social History of the Machine Gun by John Ellis talks about this, and may be where I read about the Japanese film--it's been twenty years since I read it.
They did manage to bend the snot out of a SMG barrel. Ma Deuce shrugged it off, as did the .30 cal LMG.
Ping for later.
They just "call" them damascus steel. They are not the real deal nor are they similar in properties.
These custom blades are produced either through acid etching.
Or through slightly different metals being heated, folded, hammered and otherwise manipulated just enough to produce a 'Damasus pattern' or 'Damascus effect'.
If the rope were strong enough, it would keep the sub from expanding, and therefore it would be unable to rise to the surface.
Do you work for Alcoa?
Ping.
