This is a Classic Tested Case XX folding knife. It would be called near mint condition with the original factory edge except for the staining on the blade which occurred due to climate change (please see pictures). This is a rare trademark etched  bolster and is number 019 of only 50 made. So stained, but one of the rarest Classic Clasps. It can be cleaned. The blade has good snap and no wobble. Comes with the original box.
