Vintage Imperial Prov. R.I. USA Tilt-Lock Pen Knife | Swirl Celluloid Handle | Mid-Century American Pocket Knife

This vintage Imperial pen knife from Providence, Rhode Island blends clever design with classic mid-century styling. Featuring a single blade with integrated cap lifter and Imperial’s innovative tilt-lock mechanism, it’s both a functional tool and a fascinating collectible.

The handle is fitted with creamy swirl celluloid scales, capped at both ends with nickel silver bolsters. What sets this knife apart is its unique locking mechanism: to release the blade, you tilt the knife downward—disengaging the internal bearing. To lock again, simply tilt once more. No buttons, no springs—just simple American ingenuity.

📜 Historical Note:
Founded in 1916, Imperial Knife Co. became a household name through the 1940s–1970s, known for durable, affordable knives that were often a young person’s first pocket companion. This model showcases their tilt-lock patent design, developed to create a safe, locking knife without costly engineering. These were often carried by tradesmen and workers, where function, safety, and price all mattered.

Whether you’re adding to a collection, restoring a classic, or simply looking for a conversation piece, this knife is a great example of accessible postwar American cutlery.
