Okay, phase two. After the fortuitous events leading to my melting contaminated (Tin and antimony) copper and the resultant, resounding success I chose to accept my sorry luck and pursued the idea.
And work it I did. See, my man Konrad reckoned, and I think correctly, that the maker of Otzi's axe had peened in the two, long sides which not only gave it a sexy shape but also raised the two flanges you see on the surface. Told you last time to remember the flanges.
Being that this is a striking tool, there's no brain-strain in seeing how handy those flanges were in the finished product. We'll talk about flanges again.
Back to the top picture; you'll notice my first pattern, far left, was made with a certain amount of the sexy curve down both sides already in place. Mistake. It made the entire thing too skinny as you can see, so...
Second from the left; my new pattern. Everything is beefed-up a bit to allow for metal shrinkage and, most importantly, other than the slight curve on the cutting edge, the shape is a straight-sided trapezoid.
The end result is the little spud you see both at the end of the line-up above - and below.
So, I took the chunk pictured above (Weighs just under half a pound) and worked down the two sides.
Notice above, post hammering the surface seems to have hives. Those appear to be blisters (bubbles?) which I assume means some impurity in the metal showing up as a plane of weakness when the copper was compressed. Still naught to make a song about.
I'd been worried that my beating had over-hardened it so I annealed it and beat on it some more.
One more glam shot of Otzi's axe, just after quenching.
More about the flanges later.
