Designed by Spencer Marquardt, the QSP Jumping Jack is a compact slip-joint pocket knife that combines traditional non-locking operation with contemporary materials. Its 70 mm blade is made from 14C28N stainless steel, hardened to 59–61 HRC and finished with a clean satin surface. A flat grind provides practical cutting geometry for everyday utility tasks. The black-and-white resin handle gives each knife a distinctive appearance, while bronze pivot washers support smooth operation. At 89 mm closed and approximately 90 g, the Jumping Jack has compact proportions without feeling insubstantial. It is supplied without a pocket clip and comes presented in a QSP gift box.
