We will begin with a unique source of the information on "poor-quality" kites.
I would like to attract attention of my colleagues to a word METAL.
Metal instead of habitual high-proof silver.
Simple metal which is
a) any of a number of chemical elements, such as iron or copper, that are often lustrous ductile solids, have basic oxides, form positive ions, and are good conductors of heat and electricity
or
b) an alloy, such as brass or steel, containing one or more of these elements
That’s why when I hear word “metal” (especially after multiplying this word by 70 years!) I expect to see something that maybe not completely “eaten away with rust”, but have some usual footprints of time (at least!). “Usual” for 70 years old metal pieces. Don’t you?
