That rust on the handles must have been put on by the special effects department .. no hang on ... its its its a...LEATHERMAN
I gotta come to LM's defense here. I don't exactly baby my multi-tools and I've owned probably at LEAST a dozen LM's over the years and I've NEVER had one rust. And I live in the nice humid Ozarks too. Although I did own a Gerber and it started rusting within a week. 
Well as life seems to do at times, I must eat my words. I was dragging all my multi-tools out for a group pic and it seems that in the last year my LM mini-tool has developed a bit of surface rust. I keep my Mini-tool in my junk drawer. This is the 1st time I've ever seen a LM rust but I am man enough to admit it. Although, I would like to state though that my Mini-tool has the black oxide finish and is never used. So I can still boast that, with the exception of the black oxide LM's, I've never seen one rust.

But it may all be for moot anyway as I'm getting a Vic Spirit S soon.
