While I liked the idea of the metal saber hilts when first discovered, the overuse of the Obi-Wan and generic/Kit Fisto saber hilt accessory got kind of annoying. However, to my great dismay, I noticed during a recent examination that one of the generic hilts - I am think it came with Ani HD - is most assuredly rusting around the rings! There's also a bit of tarnish over the surface of the hilt which seems to be causing some extra tightness for the saber blade that didn't exist when I got it. Since there's a paint dot on one side, I can't clean the rust and tarnish off without taking that off as well.
On the other hand, the Obi-Wan hilt I have right here is clean and shiny, totally free of rust and tarnish. I believe that is because unlike the generic hilt, the Obi-Wan hilt is chromed and painted at the rings while the generic isn't.
Just thought you should know.
