Vintage 1950s Hammer Brand Pen Knife – Red Swirl Celluloid Handle – USA Made – 1 Blade – Keyring – Mid-Century Pocket Knife

This charming little pen knife dates to the 1950s or early 1960s and bears the recognizable Hammer Brand stamp on the tang — a beloved name once distributed through New York’s Imperial Knife Company. It features a striking red swirl celluloid handle with brass pins and steel liners, showcasing the simple yet colorful aesthetic that made mid-century pocket knives a staple of everyday American life.

This single-blade pen knife was designed for practicality, with a slim, lightweight build ideal for pocket carry, and a built-in keyring loop to clip to a keychain, belt loop, or tackle box. While compact, it still retains a touch of visual flair with that fire-like red handle and highly polished carbon steel blade.

Whether you're a seasoned collector or new to the world of vintage blades, this is a great entry piece that blends function, form, and nostalgia.
