on the fifth sevii island(i am not sure about which island), there is a man near a tower of stone (the grave of his dead onix 'tectonix').There you may find a pokeball which has metal coat. You may use metal coat to evolve onix into steelix and scyther into scizor.
It doesn't evole at a level, it evolves into Steelix when traded holding a Metal Coat.
Onix evolves into Steelix when it is holding a Metal Coat and traded to someone else.
the way you can evolve an onix is by letting it hold a metal coat and trading it to a friend and then making them trade it back onix evolves when your trade parterner receives onix.
You must Trade Onix while it is holding a Metal Coat in order to Evolve into a Steelix.

Onix evolves into Steelix when you trade Onix while holding a metal coat.
Yes, you can. If the Onix is holding a metal coat, it will not prevent you from trading it, and the recipient will receive a Steelix (because Onix being traded with a metal coat will make it evolve into a Steelix).
if you cach an onix there is a posibility that it could be holding a metal coat
