The Case XX Trapper Color Infusion Stripes of Service Blue Line honors the courage and commitment of law enforcement professionals with bold styling and dependable build quality. This full-size Trapper measures 4 1/8 inches closed and carries the classic dual-blade configuration—clip and spey—each crafted from Case’s mirror-polished Tru-Sharp surgical stainless steel. Built for performance and corrosion resistance, these blades hold an edge well and open smoothly for daily tasks or field use.
The handle is made from durable smooth white synthetic and features a vivid Blue Line design applied using Case’s proprietary Color Infusion process. This graphic doesn’t just look good—it carries a clear message of support and appreciation for those who protect and serve. Nickel silver bolsters, brass pins, and liners bring structure and shine to the build, giving this knife a solid feel in hand without sacrificing elegance.
With a weight of 3.8 ounces, it strikes a balance between pocketable and substantial. Whether you're carrying it as a working blade or keeping it as part of a service-themed collection, the 9578 Trapper is as dependable as it is meaningful. Like every Case knife, it's proudly assembled by skilled hands in Bradford, Pennsylvania, carrying the stamp of generations of American craftsmanship.
