Never used Swiss Army knife purchased somewhere in the midwest by a truck driver on the road who stopped for a break at a TA Truckstop in the late 1980's. While there are only six tools extended in the photo, two of them have double duties. In addition to the small and large blades at each end, the can opener can also be used as a small screwdriver and the bottle opener has a larger screwdriver and a wire bender (tiny notch at the base). On the back of the knife are a phillips screwdriver and an awl/punch with a handy eye hole for emergency sewing repairs. The eye in the awl was added in 1985. Measures 3-1/2 inches.
