Victorinox Elinox Alox Pioneer - Blue Alox Duo 2205. This 2 blade blue alox Swiss Army knife is made by Victorinox and has the Elinox with Crossbow tang stamp on the front side. The Victorinox 4 line stamp is on the back side tang. The second smaller blade is the older clip pointed style blade which has been discontinued. This knife is known by the Victorinox model number 2205. Some are calling it the Duo since it has 2 blades but that is not going to be correct name that Victorinox actually used. Elinox is a trademark used by Victorinox starting in 1957 up until the mid 1970's.
This knife is currently for sale on my eBay.
