After posting "A modern-day Soldier" a week ago, I learned of an error on the SwissArmy.com page announcing the new Victorinox Soldier -- the knife being sold right now in the U.S. is not equipped with a seat-belt cutter. That tool doesn't appear in the photo of the knife, but it is listed in the accompanying description.
I should know better than to trust the copywriter.
As far as I can tell, four other 111mm Victorinox knives actually do feature a belt cutter: the Workchamp, the Parachutist, the Fireman and the Rescue Tool.
Second, I'd like to make up for omitting the Victorinox Farmer from my discussion of worthy Swiss knives.

The additional blade brings with it another backspring and a second liner, making the package about 3/32" thicker than the traditional Soldier. Still, the Farmer is relatively slim, along with being rock-solid and undeniably classy.
It's affordable, too -- just $28 from FelineVet, a kind-hearted vendor who's well-known to Swiss Army Knife aficionados. As of this writing, for two bucks more FelineVet also offers a version with red Alox scales, reportedly produced in limited numbers in 2007.
Personally, I'd splurge for the red one.
