The Spartan is a direct descendant of the historic Victorinox Officer's Knife, having essentially the same toolset as the original knife, but the modern versions of the tools.

Nearly all Victorinox 91mm Swiss Army knives contain the six main tools, and two scale tools of the Spartan. So it can also be considered to be the base full length 91mm Swiss Army Knife - to which all the other models add (and occasionally subtract*) tools. 
* Tinker based SAKs swap the corkscrew for a Phillips screwdriver; 
Compact based models swap the small blade, openers and awl for the Combo Tool; plus a few other minor variations in other models.

It is available in numerous colors and handle designs, such as the beautiful city and landscape series, which contain images of iconic views around the world, such as the Matterhorn in Switzerland or the London Skyline.
