Camillus Pen Knife No. 21 – USA Made – Black Jigged Delrin Handles – 2 Blade – Circa 1960–1976

This Camillus No. 21 pen knife is a classic example of mid-century American pocket cutlery—built for everyday use with a focus on durability, simplicity, and clean design.

Featuring a two-blade configuration with a long clip point master and secondary pen blade, this knife carries the unmistakable look of a traditional gentleman’s or utility pen knife. The black jigged Delrin handles provide a rugged, workmanlike aesthetic while maintaining excellent durability—an innovation that became increasingly common during this era.

Historical Note

Camillus Cutlery Company, founded in New York in 1876, became one of America’s most prolific knife manufacturers. By the mid-20th century, Camillus was producing millions of knives for civilians, tradesmen, and even the U.S. military.

The No. 21 pattern reflects this era of practical American manufacturing—when knives were made not as collectibles, but as reliable daily tools carried by generations of working men and women.
