A **wooden clamp toy** (often called a “cramp” or “extending” toy) is a classic mechanical gadget that demonstrates the power of a simple scissor-linkage mechanism. Crafted from durable hardwoods like beech or maple, these toys consist of a series of intersecting wooden slats connected by pivot pins, allowing the structure to expand and contract with a satisfying, rhythmic motion. When the handles at one end are squeezed together, the accordion-style body lunges forward, mimicking a grasping hand or a snapping creature. It’s a tactile, low-tech wonder that introduces children to basic engineering and physics through playful, hands-on interaction.
