I suspect the discoloration is mineralization or surface "rust" on the black oxide; should be able to be cleaned up with a little TLC. The G10 scales are a very dark green (don't remember what they called this color) and have no chips or gouges. Kydex sheath comes with a Blade-Tech Tek-Lok.
Blade retention is very good. I'm not 100% on the vintage, I think around 2012.
