Here's to the handcrafted!
http://en.m.wikipedia.org/wiki/Achim_Leistner
Achim Leistener was coaxed out of retirement to craft the Silicon Spheres for the Avogadro Project. He is thought to be the person who has created the "roundest" object in history. Machines aren't able to match his work.
Its humbling when you see something as crafted by hand as this. I wonder how he could do at sharpening?
With the revision of Avogadro's Constant, be prepared to adjust your scales (presuming we are working to many decimal points of a Kg).
