This is a vintage Art Deco gentleman\'s pocket watch fob pen knife made by the A&Z Chain Company.
Manufacturer: The \"A&Z\" stamp on the tang of the smaller blade belongs to the A&Z Chain Company, which was founded in 1905 in Providence, Rhode Island by Carl Anshen and Saul Zeitlin. They specialized in high-quality gold-filled jewelry, watch chains, and personal accessories.
Estimated Era: Based on the engine-turned pinstripe design, central diamond cartouche (left blank for custom initial engraving), and overall profile, this knife is from the Art Deco era (circa 1920s–1940s).
Outer Scales (Handles): The handles feature an ornate border pattern and are gold-filled (rolled gold plate), a standard luxury finish for jewelry-adjacent tools of this period.
Blades: The steel elements are stamped \"STAINLESS\". It includes a classic small pen knife cutting blade and a long, slender multi-tool blade featuring an integrated nail file tip.
The Bail/Loop: The loop at the end allowed it to attach securely to a vest\'s pocket watch chain (fob chain) or a key ring.
Did home gold test and the result was 12k to 10k GF.
Dimensions: Closed, the knife body measures just under 2.25 inches, making it an elegant, low-profile pocket accessory.
