Abstract:
The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and a tungsten weight member coupled to the toe and a tungsten heel weight member coupled in a hosel cavity.

Claim (Index 1):
A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees, a first club head mass and a first Moment of Inertia about the y-axis, a second club head having a loft of between about 26 and 35 degrees, a second club head mass and a second Moment of Inertia about the y-axis, and a third club head having a loft of about 36 degrees or greater, a third club head mass and a third Moment of Inertia about the y-axis,\n the first club head comprising: a first body made of steel comprising a first heel, a first toe, a first topline, a first sole, a first hosel, and a first back wall, a first face insert made of steel and having a first face insert mass that is welded to the first body to form a first hollow cavity between the first face insert and the first back wall; a first toe weight member formed of tungsten and coupled in a lower toe portion of the first hollow cavity that has a first toe weight member mass that comprises greater than 25% of the first club head mass; and a first heel weight member formed of tungsten and coupled in a first hosel cavity of the first body such that a shaft axis intersects the first heel weight member below the first hosel, the first heel weight member comprising between 5% and 10% of the first club head mass; wherein the first face insert mass is less than first toe weight member mass and a Moment of Inertia about the y-axis to blade length ratio is greater than about 3 kg-mm.
