На картинке изображены колки замковые с Bi-металическим покрытием Ruthenium/Gold и "крутилкой"--Knurled Knob.
Немного о покрытии Ruthenium:
"Ruthenium is an extremely hard, shiny metal and is found in association with platinum ores. It is very rare; no more than 120 kilograms are produced per year. This accounts for the high cost of ruthenium; it is more expensive than both gold and platinum.
The name ruthenium originates from the Latin “ruthenia” which means “Russia”, the home of the discoverer of ruthenium.
At room temperatures, ruthenium keeps its shiny, metallic surface and does not tarnish. Acids cannot damage it when it is deprived of oxygen."
