The Deadline opens with Kershaw’s KVT ball-bearing system. But a manual system like that has to have detent—often strong detent—to keep the blade in the handle until the user opens it. When the blade is fully closed, a depression in the blade is engaged by a ball partially embedded in the liner or handle. The interaction of ball and depression keeps the blade closed. But sometimes the detent can be too strong. The answer is our new Tuned Detent System (TDS). TDS puts the detent ball on the front scale of the knife in an inset steel plate. This plate enables us to “fine tune” the detent so that it’s perfect—not too heavy, not too light.
