That is interesting. This is steel cable not stainless though.
Seems like steel can last indefinitly if kept greased.
Also steel appaently is easy to inspect and stainless is effectivly impractical to inspect.
At least that's what it is starting to sound like.
My understanding is stainless can work harden- then fail abrutly without warning, and undetected even by close inspection. Maybe this is the down side to stainless.
