Golf club set having similar properties

A set of golf clubs comprising:

• a plurality of iron-type golf clubs, each iron-type golf club comprising:
• an iron-type golf club head having a striking face configured for striking a ball, a body extending rearwardly from the striking face, and a face thickness, the body having a top surface, a sole, a heel, and a toe, and a hosel including a hosel axis, wherein the iron-type club head is perimeter-weighted and includes a rear cavity;
• a shaft configured to engage with the iron-type golf club head at a first end and a grip engaged with the shaft at a second end opposite the first end;
• wherein each of the plurality of iron-type golf clubs has a length, a lie angle, a weight, a swing weight, and a center of gravity;
• wherein each of the plurality of iron-type clubs include an iron-type golf club ground plane origin point located at the point at which the ground plane and the hosel axis intersect and a hosel origin point located on the hosel axis and coincident with an uppermost edge of the hosel;
• and
• wherein each of the plurality of iron-type golf club heads comprise a x-axis, a y-axis, and a z-axis that pass through the ground plane origin point;
• wherein:
• the x-axis is parallel to the ground plane and parallel to the striking face;
• the y-axis is perpendicular to the x-axis and extending rearwardly from the striking face;
• and
• the z-axis is perpendicular to the ground plane and extending in a direction from the sole to the top surface;
• and
• wherein each of the plurality of iron-type golf clubs further comprise an x′-axis, a y′-axis, and a z′-axis that pass through the hosel origin point;
• wherein:
• the z′-axis extends along the direction of the shaft axis,
• the y′-axis is perpendicular to the z′-axis and extends toward the rear of the golf club head;
• and
• the x′-axis extends perpendicular to the y′-axis and the z′-axis;
• and
• a distance ΔX is measured from the hosel origin point to the center of gravity along the x′-axis, and a distance ΔY is measured from the hosel origin point to the center of gravity along the y′-axis;
• wherein each of the plurality of iron-type clubs has a different loft angle in the range of 23 degrees to 60 degrees;
• wherein the lengths are substantially equal;
• and
• wherein the lie angles are substantially equal;
• and
• wherein each iron-type golf club has a different face thickness than all other clubs within the set;
• and
• wherein the plurality of iron type golf clubs comprises:
• a first iron-type golf club having a first loft angle and a first face thickness;
• and
• a second iron type golf club having a second loft angle and a second face thickness;
• wherein the second loft angle is greater than the first loft angle;
• and
• wherein the second face thickness is greater than the first face thickness;
• wherein a distance between the center of gravity is within 2 mm of a distance between the iron-type golf club ground plane origin point in the y-axis direction for the plurality of iron-type clubs;
• and
• wherein each of the iron-type golf club heads has a moment of inertia with respect to the hosel axis within about 200 g*cm2 of each other;
• wherein each of the plurality of iron-type golf club heads have a ratio of a center of gravity location measured from a hosel origin point ΔX to ΔY that is consistent between each of the plurality of iron-type golf club heads, wherein the ratio is within a range of 2.6 to 3.0.
