Stainless steel hammers for stainless bolts
Emanuele Pellizzari , who sells his Kinobi bolts, informs that you need to use a stainless steel hammer for stainless bolts.
"To keep is extremely simple. Stainless steel is a material that self defend itself. It can defend itself till a certain degree of attach from external agents. If you dirty it, with less resistant materials (as an example a hit of a
hammer not made from stainless steel), you start a galvanic corrosion.
Galvanic corrosion, first attach the less noble material which actually protects the stainless material it will dissolve, but then it attach ALSO the stainless steel. When? No clue, it depends on where it's placed and how corrosive the environment is.
So, never hit with a hammer made from steel a bolt of stainless steel, because otherwise:
a) it dirty the bolt up, starting galvanic corrosion on the traces
left of the less noble material.
b) eventually, the corrosion left by these particles, will corrode ALSO the stainless steel.
c) in case you hammer the bolt by mistake with a a not suitable hammer, you can try to clean it with this piece (for polishing shoes).
