    Case Sowbelly Knives

    The Case Sowbelly takes its name from the deep, rounded swell along the front of its handle, a curve that looks like a sow's belly and fills your hand the moment you grip it. Inside that 3 7/8-inch closed frame, Case builds a three-blade stockman in Bradford, Pennsylvania: a clip blade, a sheepsfoot coping blade and a spey blade, all opened by traditional nail nicks on a slip joint backspring.

    Those three blades are why the Sowbelly earns its pocket space. The clip is the longest blade and does the everyday cutting and detail work. The sheepsfoot coping blade keeps a straight edge with no sharp point for controlled, clean cuts. The spey, once a ranch blade for working livestock, gives you a rounded, forgiving tip for skinning, trimming and utility chores. Every Sowbelly comes in Tru-Sharp stainless or Carbon Steel, so you can choose low maintenance or the easiest edge to resharpen.

    It's built for ranchers, hunters and everyday carriers who want three distinct edges in one traditional knife, and for collectors who want one of Case's most recognizable stockman frames. At Knifeworks, you're buying from an authorized Case dealer, and every Case Sowbelly is covered by the Case Limited Lifetime Warranty.

    What makes a Sowbelly different from a stockman?A Sowbelly is a stockman with a bigger belly. It keeps the classic clip, sheepsfoot and spey blade layout, but its handle swells deeply along the front edge, giving you a fuller, more secure grip for hard cutting than a standard stockman frame.

    The Case Sowbelly Knife Buyer's Guide (2026)

    What makes the Sowbelly a stockman with a difference, and how its clip, sheepsfoot and spey blades each earn their place.

    The Case Sowbelly: A Big-Bellied Three-Blade Stockman+

    The Sowbelly is named for its silhouette: the front edge of the handle swells out in a deep, rounded curve, much like a sow's belly. That swell is what you feel first. It fills the palm, locks your fingers in place and gives a 3 7/8-inch closed knife the grip of something larger.

    Case builds every Sowbelly in Bradford, Pennsylvania as a traditional three-blade stockman. Every blade opens with a traditional nail nick and rides on a slip joint backspring.

    TipRead the pattern stamp. Every Case Sowbelly stamp ends in 339: the 3 is the blade count and 39 identifies the Sowbelly pattern. The suffix tells you the steel, SS for Tru-Sharp stainless or CS for Carbon Steel.
    Three Blades, Three Jobs: Clip, Sheepsfoot & Spey+
    BladeShapeBest For
    ClipThe longest blade; a clipped spine drops to a fine, controllable pointEveryday cutting, opening packages, food prep, detail work and piercing
    Sheepsfoot CopingStraight edge; the spine curves down to meet it with no sharp pointControlled straight cuts, trimming, whittling and work where a point would slip or puncture
    SpeyShort, rounded blade with a blunt, upswept tipSkinning, trimming, scraping and utility chores where a forgiving tip matters

    Spreading work across three blades keeps each edge sharp for the job it does best. Let the spey or sheepsfoot handle tape, cardboard and rough work, and save the clip for clean slicing.

    Sowbelly vs. Standard Stockman+

    If you already like the stockman's three-blade layout but want more handle to hold onto, the Sowbelly is the natural step up.

    The Spey Blade: From Ranch Tool to Everyday Utility+

    The spey blade is the Sowbelly's link to its stockman roots. It began as a ranch blade for working livestock, and its short, rounded profile with a blunt tip is still what makes it useful today: it cuts and scrapes without a sharp point that can slip or puncture.

    On a modern Sowbelly, the spey is the blade to reach for when skinning game, trimming hide or cord, scraping, or cutting close to a surface you need to protect.

    TipKeep the spey sharp along its full curve. Its rounded edge works by rolling through the cut, so a consistent edge from heel to tip matters more than a fine point.
    Choosing Your Steel: Tru-Sharp SS vs. Carbon Steel+
    SteelEdgeMaintenancePattern Suffix
    Tru-Sharp StainlessGood, easy touch-upLow, strong corrosion resistanceSS
    Carbon SteelTakes a keen edge with the least effortHigher, wipe dry and oil to prevent rust; develops a patinaCS

    Tru-Sharp is Case's surgical stainless and the right pick for a Sowbelly that will see sweat, rain or kitchen work without much attention. Carbon Steel suits the traditionalist who sharpens on a pocket stone and likes the gray patina that builds over years of use.

    TipWith three blades, a carbon steel Sowbelly needs oil in three pivots. A drop at each joint every few months keeps the action smooth and the blades rust-free.
    Slip Joint Action and Everyday Care+

    The Case Sowbelly is a slip joint, so there is no Liner Lock or Frame Lock to release. Backspring tension holds each blade open and closed, which makes it a knife for controlled cutting rather than prying or hard impact.

    Open each blade by its nail nick, close it with your fingers clear of the edge, and let the backspring snap it home. Blow out pocket lint, wipe the blades after cutting food or tape, and oil each pivot every few months.

    Case Sowbelly: Frequently Asked Questions

    Answers from the Knifeworks team in Columbia, Louisiana on the Case Sowbelly knife.

    What is a Case Sowbelly knife?+

    The Case Sowbelly is a traditional three-blade stockman built in Bradford, Pennsylvania. It carries a clip blade, a sheepsfoot coping blade and a spey blade in a slip joint frame 3 7/8 inches long closed, with a handle that swells deeply along the front edge.

    Why is it called a Sowbelly?+

    The name comes from the handle's shape. The front edge swells out in a deep, rounded curve that resembles a sow's belly, and that swell is what gives the knife its full, secure grip.

    What's the difference between a Sowbelly and a stockman?+

    A Sowbelly is a stockman with a bigger belly. It keeps the stockman's clip, sheepsfoot and spey blades, but its handle has a much deeper swell along the front edge, giving more palm fill for heavier cutting than a standard stockman's slimmer frame.

    What are the three blades on a Sowbelly used for?+

    The clip blade is the longest and handles everyday cutting and detail work. The sheepsfoot coping blade has a straight edge and no sharp point for controlled, clean cuts. The spey blade has a rounded, blunt tip for skinning, trimming and scraping.

    What is a spey blade?+

    A spey blade is a short, rounded blade with a blunt, upswept tip. It began as a ranch blade for working livestock, and today it is valued for skinning, trimming and utility cuts where a sharp point could slip or puncture.

    Which steel is best on a Case Sowbelly?+

    Tru-Sharp stainless, marked SS in the pattern stamp, is the low-maintenance choice with strong corrosion resistance. Carbon Steel, marked CS, takes a keen edge with the least effort and develops a patina, but needs to be wiped dry and oiled.

    Does the Case Sowbelly lock?+

    No. The Case Sowbelly is a slip joint, so there is no Liner Lock or Frame Lock. Backspring tension holds each of the three blades open and closed.

    What warranty comes with the Case Sowbelly?+

    Every Case Sowbelly is covered by the Case Limited Lifetime Warranty. Knifeworks is an authorized Case dealer, ships same or next business day from Columbia, Louisiana, and answers questions at 888-225-9775.
