But *anybody* can (in theory) make a highly accurate duplicate of *the*
standard kg reference object. Get a balance scale as accurate as you want
the copy to be. Stick the standard weight on one pan. Stick a block you
know to be just over a kg on the other. Shave little bits off until balance
is achieve. Viola! Reference copied.
Low tech, but it works and anybody can do it. Make several of these to ship
to every country in the world. They do the same thing there to make as many
local copies as they want.
A major problem with using a sphere is that atoms don't line up in neat
little spherical arrangements. They do lattices. Any lattice cut to a
sphere has "jaggies" like a pixelated curve.
