Looking for a pocket knife that’s both functional and a real conversation starter? The QSP Jumping Jack Blue Bone might be just what you need. Designed by Spencer Marquardt, this slip joint knife features a razor-sharp 14C28N stainless steel blade with a clean satin finish and a smooth flat grind. But what really sets it apart is the stunning blue bone handle—bold, colorful, and totally unique. It opens smoothly thanks to copper washers, and at just 3.28 oz, it’s lightweight enough for everyday carry without skimping on style or performance. Whether you're into collecting or just want something a little more refined for your EDC, the Jumping Jack strikes a perfect balance.
