I picked up another Explorer Plus from Ebay. Its supposed to be new in box from an estate sale. It has the older blade tang stamp (which I believe is pre-2005, and the older magnifying glass style (pre 2007). What I noticed different about this knife is the box, which has the warranty information printed on the inside of the package sleeve. Anyone know when Victorinox stopped using this type of packaging. I would just like to know the approximate age of my new knife. If anyone could shed some light on this, I'd appreciate it.
