NYC Souvenir knife! We're not sure what the outside is made of, some type of treated/hardened leather is our guess, but it is dark red and smooth, with gold embossed letters "Souvenir of New York City." Working pocketknife, so open and close with caution! Details: Antique Souvenir Pocket Knife NYC Brass sides, stainless interior Measures just under 2" 30" vintage sterling silver box chain
