A type of low quality steel , typically in tools. Most samples are low quality mild steel, or overhardened carbon steel. A good way to tell if an object is made of chinesium is checking the stamp. If the stamp says "H.S.S.", "HSS" or similar and is labeled "Made in China/Taiwan" it is probable chinesium. Another way to see is if it breaks or becomes dysfunctional very quickly.
Damn, that drill bit is dull as heck and it snapped in half... Definitely chinesium.

Wow, look at those chinesium screws. They are already stripped.
