The little knife was made for carrying on a fob. Most likely intended for ladies. It is plated and some of the plating has come off. The color and detail aren't clear in the photos... might be plated chrome... and we would need a closeup of the stamp to see the branding and/or country of origin. The blade also appears to be plated. The blade has the original edge and has not been resharpened. Also, I can't see from the photos if the handles are solid or covered in thin metal. If they are covered in thin metal, it may be a "skeleton knife" that was made without covers and finished by a jeweler. Inexpensive ones were covered in copper or plated with chrome. More expensive ones were covered or plated in gold.
