Stroup Sd1 2.5" Acid Etched Blk
The Stroup SD1 is a compact fixed blade knife built for serious work in the field or backcountry. Handmade in the USA from 1095 high carbon steel, this 2.5-inch blade delivers the kind of toughness you need when a knife has to perform without question. The acid-etched finish gives it a no-nonsense look while the double-edged geometry and chisel-ground tip make it equally capable at precision tasks and heavy-duty cutting. At just over 5 inches overall, it's small enough to stay out of the way but substantial enough to handle real survival and tactical applications.
The SD1 strikes a practical balance between compact carry and genuine cutting power. Its design prioritizes reliability over flash—no unnecessary features, just steel that holds an edge and geometry engineered for penetration and control. Whether you're processing wood, preparing food, or working through cordage and hide, the high-carbon blade takes and holds a keen edge. The acid-etched finish is both functional and durable, resisting corrosion while showing character over time.
The knife ships with a Kydex sheath and IWB (inside-the-waistband) nylon belt clip, giving you flexible carry options. The sheath is purpose-built for the SD1's dimensions and keeps the blade secure and accessible. If you're looking for an American-made fixed blade that doesn't compromise on material or build quality, the SD1 is built to earn its place in your gear rotation.
