Some models of Victorinox knives were produced as special run in extremely limited quantity (sometimes – for specific brand). Mechanic Jr. (or Special Mechanic) is an example of such a model. It’s very valued (by true collectors, of course!) knife and relatively rare.
As probably all SAK-interested people know, this is the smallest (91-mm) model of Victorinox knives, which includes pliers. It looks like Compact, but there is no hook in this model, pliers instead of scissors and Phillips screwdriver instead of corkscrew. Besides these differences, both are almost twins.
Update (2017-07-18): I got an original Mechanic Jr.!
