Vintage John Primble Pen Knife | Circa 1940s–50s | Belknap HDW & MFG Co | Yellow Synthetic with Fish Shield

This vintage two-blade pen knife is a genuine piece of mid-century American cutlery, stamped JOHN PRIMBLE / BELKNAP HDW & MFG CO—a mark that connects it directly to one of the nation’s most iconic hardware suppliers. Produced in the 1940s–50s, this knife represents Belknap’s dedication to quality during the golden age of American toolmaking.

Its bright yellow synthetic handles and nickel silver fish shield give it a classic, workaday appeal. These were the kinds of knives sold across general stores and hardware counters from Kentucky to Kansas—tools meant to ride in pockets, sharpen pencils, slice twine, or open a day’s mail.

🧲 Historical Note:
Belknap Hardware was a Louisville powerhouse, known for supplying everything from firearms to fencing to farmers and tradesmen. The “John Primble” line was their pride—representing a blend of old-world steel and American practicality. This knife’s full tang stamp indicates it was made before outsourcing practices began, likely by contracted U.S. cutlers using high-carbon steel and traditional build methods.

🧷 Collector’s Note:
Primble knives with the full “Belknap HDW & MFG CO” tang are increasingly scarce and desirable, particularly with original yellow scales and the fish shield intact. It’s a fine addition to any Belknap display or vintage pocket knife lineup—especially for those who favor honest tools with working-class roots.
