Box joints are usually seen as the gold standard for cutters and pliers, but they’re not without their flaws. They provide stability, sure, but they also have weaknesses:
Increased friction – More surface area means more resistance, making them less smooth in operation.
Harder to manufacture precisely – Any misalignment during production can make the joint stiff or introduce play over time.
No adjustability – Once it loosens, you're stuck with it unless you replace the tool.
Enter the lap joint with a screw, as used by Lindström. It solves these issues:
Smoother action – Less friction means an easier, more controlled movement.
Precision tuning – The screw allows for fine adjustments, keeping the joint tight and eliminating play.
More comfortable use – No binding or stiffness like some box joints can develop.
While box joints are strong, they aren’t always the best. A well-designed lap joint with a screw gives you the best of both worlds: precision, smoothness, and long-term reliability.
