The Victorinox Grand Prix is a four-layer Swiss Army knife. This model was introduced in 1980 and in the following years (up until about 1995) it underwent the usual changes in tools like the addition of the hook in 1991.
The unique feature of the Grand Prix is the inlay of a classic Ford Model T on the front scale. The inlay was originally nickel silver, later versions were stainless steel. Some of the finer details were omitted in the stainless versions.
