Many Wenger pocket knives have a nail file. On the 85mm pocket-sized knives, it is in the same layer as the main blade. On the 65mm keychain knives, it's usually next to the small blade. This is one of the biggest differences between Wenger and Victorinox knives, since Victorinox usually has nail files on models that are 74mm or smaller, but almost never includes them on its larger knives (the only current exception is the Sportsman).
