Nice axe Simon.

Out here the humidity can also play it's part with corrosion too. Where nDRo1d lives it does get quite damp & cold in winter and generally a lot drier heat in summer but still an area where most of the severe thunderstorms come from which also builds up the humidity.

Like most things, if well maintained and looked after it should be fine. Just a little bit more of a challenge in coastal regions where salt air will corrode anything metallic.
