Technology that stabilizes the clubhead by moving weight out and away from the center of the clubface. By distributing an object's mass toward the outer boundaries, it increases the Moment of Inertia, (MOI) which in golf makes the club less resistant to twisting on off-center hits and hence more forgiving.

Club design used in cavity-backed clubs that has weight distributed around the outside of the club head, enlarging the sweet spot.

Redistributing weight on a club head to the heel and toe in an attempt to stabilize the club on all types of impacts.
