The sowbelly knife is one of the more distinctive patterns in the world of traditional pocketknives, recognized not for its blade arrangement but for its signature curved handle. First appearing in the early 1900s, the sowbelly pattern quickly earned a place among working knives of the era, thanks to its ergonomic shape and multi-blade versatility. While it never quite reached the widespread popularity of its more straightforward cousin, the stockman, it held a loyal following throughout the first half of the 20th century. By the 1940s, the stockman pattern began to dominate factory production, gradually pushing the sowbelly into the background. But it was never forgotten. That pronounced curve, which gives the knife its name, has kept it instantly recognizable and ensured its survival across generations of knife collectors and users.

The name sowbelly refers to the handle’s deep serpentine curve, which resembles the rounded underside of a sow pig. The design isn’t just a visual gimmick, it’s practical. The inward bend of the handle fits more naturally into the user’s palm, making the knife feel more secure and comfortable during heavier use. Whether it’s cutting rope, slicing through leather, or managing day-to-day utility tasks, the sowbelly’s shape gives the user better leverage and less hand fatigue. It also allows the blades to sit deeper in the frame when closed, keeping the knife from becoming overly bulky in the pocket.

While many sowbelly knives stick to the stockman’s familiar three-blade setup, a clip point, sheepfoot, and spey blade, they’re not limited to that configuration. Some have two blades, some have four, and a few break tradition altogether with specialty blades. The blade variety adds to the pattern’s versatility, but again, the curved handle defines the sowbelly and sets it apart from other jack knives.

Because they were never as mass-produced as stockman knives, early sowbelly models are harder to come by, particularly those made before World War II. Their relative rarity and the uniqueness of the pattern make them attractive to serious collectors. Yet the sowbelly isn’t stuck in the past. Companies like Case and Frost Cutlery continue to make it a part of their core lineup, often releasing it in a wide range of handle materials, from traditional jigged bone and stag to more modern acrylics and synthetics. Rough Ryder has brought renewed attention to the pattern with budget-friendly models that don’t sacrifice visual appeal or build quality. Boker, too, has contributed to its revival with thoughtful designs in both American and European styles.

Today, the sowbelly pattern is more than just a historical footnote. It’s a time-tested knife that balances form and function in a way that few others do. Its curved shape, comfortable grip, and visual character have earned it a lasting place in collections and pockets alike. While it may have spent decades in the shadow of the stockman, the sowbelly remains one of the most memorable and functional traditional pocketknife patterns ever made.
