Some work with steel wool and a file and they’d be good as new.
If the stab wound doesn’t kill them the rust and arsenic will.
What possessed man 5000 years ago to produce arsenic? And then why use it in forging swords.
Did someone say this stuff is deadly. Look what it did to Ugg. Let’s use it to make swords!!!
Those look like they’d be relatively painful
Advantages of arsenical bronze
While arsenic was most likely originally mixed with copper as a result of the ores already containing it, its use probably continued for a number of reasons. First, it acts as a deoxidizer, reacting with oxygen in the hot metal to form arsenous oxides which vaporize from the liquid metal. If a great deal of oxygen is dissolved in liquid copper, when the metal cools the copper oxide separates out at grain boundaries, and greatly reduces the ductility of the resulting object. However, its use can lead to a greater risk of porous castings, owing to the solution of hydrogen in the molten metal and its subsequent loss as a bubble (although any bubbles could be forge-welded and still leave the mass of the metal ready to be work-hardened).[1]
Second, the alloy is capable of greater work-hardening than is the case with pure copper, so that it performs better when used for cutting or chopping. An increase in work-hardening capability arises with an increasing percentage of arsenic, and the bronze can be work-hardened over a wide range of temperatures without fear of embrittlement.[1] Its improved properties over pure copper can be seen with as little as 0.5 to 2 wt% As, giving a 10-to-30% improvement in hardness and tensile strength.[7]
Third, in the correct percentages, it can contribute a silvery sheen to the article being manufactured. There is evidence of arsenical bronze daggers from the Caucasus and other artifacts from different locations having an arsenic-rich surface layer which may well have been produced deliberately by ancient craftsmen,[9] and Mexican bells were made of copper with sufficient arsenic to color them silver.[7]

Da-da, da da da da da...
Mummm, mummm (drool)
Yep.
Swords, SWORDS IDIOT, now WORDS!
no S-words either, not allowed here
The really great thing is that those 5000 year old swords will kill you just as dead today.
Re arsenic: I would bet they were trying to create gold from other metals and came up with this alloy.
Do plowshares come before swords or is it the other way around?

Excellent discussion. - thank you!
I soak my rusted garden tools in vinegar...and voila...like brand new.
And He shall judge among the nations, and shall rebuke many people; and they shall beat their swords into plowshares, and their spears into pruning hooks; nation shall not lift up sword against nation, neither shall they learn war anymore. Isaiah 2:4
Beat your plowshares into swords, and your pruning hooks into spears; let the weakling say, “I am a warrior.” — Joel 3:10
Isaiah comes before Joel in the KJV
But are they made of a copper-arsenic alloy?
I’m guessing here, but I suspect them folks in charge at Aslantepe Mound, Malatya had laws limiting assault swords and who could own them. /S
That is how you hold power, doncha know.
