A hefty little puzzle machined from solid brass, the Gob Stopper is a sweet introduction to the wild world of burr assemblies. Twelve notched hexagonal rods come together together to form a rounded knot or "burr" that resembles a tiny metal soccer ball.

This thoroughly modern update on a traditional design required thoughtful analysis and clever machining to accomplish. A bit more challenging than a classic puzzle, Gob Stopper is well within the reach of a determined beginner puzzler.
