Callaway Big Bertha 2004 iron set (4i-SW)

Features and Benefits of the Callaway Big Bertha 2004 irons:

Big Bertha irons are aimed at mid to high handicappers.
Thinner sole reduces dragging, allowing the clubhead to slide more easily through thicker grass. Each club in the set has the same width to position the centre of gravity low and deep, creating a uniform feel and making them extremely easy to use.
'Notch' weighting ensures the club head is much less likely to twist on off-centre hits.
