The Nike OZ Black T160 blade putter achieves stability beyond its size thanks to a tungsten plug that makes up 48% of the clubhead mass. The 160 gram plug gives this putter the forgiveness of a mallet in a more compact shape.  Combining a lightweight aluminum 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% lighter than aluminum) polymer also allows for more perimeter weighting, which increases clubhead stability.  All OZ Black putters are face balanced to promote a square face at impact.  Each putter face is milled flat to precise tolerances to enhance accuracy and predictability across the clubface.  The dual site lines facilitate squaring the clubface at address to keep putts on target. Double bend stepless steel shaft.   A soft, high-tack thermoplastic rubber paddle-style grip provides for a comfortable, solid feel.
