Dual Density Weighting: Combining a lightweight aluminium body (65% lighter than steel) with high-density tungsten weight plugs moves weight away from the clubface to reduce skidding on putts of all lengths. 
Polymer Insert: In addition to enhancing feel, the soft polymer insert keeps the ball in contact with the face longer to promote a truer roll. The ultra lightweight (63% light than aluminium) polymer also allows for more perimeter weighting which increases club head stability.
Face Balanced: All OZ Black putters are face balanced to promote a square face at impact.
CNC (Computer Numerically Controlled) Milled Face – Each putter face is milled flat to precise tolerances to enhance accuracy and predictability across the clubface.
Dual Site Lines: The dual site lines facilitate squaring the clubface at address to keep putts on target. – Double Bend Stepless Steel Shaft by True Temper – C-Thru Grip by Lamkin: Soft, high-tack thermoplastic rubber paddle-style grip.
