Dang! the typeface on this monitor must be getting smaller, and I missed this post.....
why does this computer keep doing this to me
Anyway can't let a SAK thread go by, even though APS has already given you the answers.
First although Wenger SAKs do match Victorinox in quality (most of the time), the magnifying glass tool is one area where it does not.

The glass itself is too small to be genuinely useful - then it's on the end of a full length "blade" with a small scredriver tip - again SAKs are "smart" - but this Wenger design is pretty dumb, a longer tool helps in reach and access to confined spaces - the magnifying glass bulge helps negate that.... like I said not smart and not good quality.
So that brings us back full circle to Victorinox (and you probably weren't even thinking of a Wenger anyway

)
There are very few Victorinox SAKs with magnifying glass [note: the magnifying glass appears to be always paired with the in-body Phillips screwdriver - thus one gains the very useful Phillips that's designed to be used both at right angles for more torque and in-line for more reach and faster turning - good design].
The Explorer as others have correctly pointed out, is the current smallest/slimmest model.
Previously (and imported to the USA) were -
Scientist - 2 layers/backsprings
[note box shows the Swiss/international model #,
the US model # was 5068]
Yeoman - 3 layers/backsprings
