The Smith Sphere is a purpose-designed contact staff head weighing 132 g, precisely balanced for stable and consistent rolling. By placing more weight at the end of the staff, the mass shifts further from the axis of rotation. The result: noticeably increased inertia, smoother motion, and enhanced control during body rolls and other contact moves.
The Smith Sphere is fully compatible with the SpearMount system, allowing for quick and secure tool-free installation or swapping.
