Abstract
A set of iron-type golf clubs including a predetermined number of clubs is disclosed with each club including a hosel portion with a shaft operatively inserted therein and a blade portion attached to the hosel portion. The blade includes a substantially planar face portion which is generally oval in shape, a back portion which is generally oval in shape and is disposed opposite the planar face portion. The back portion includes a cavity which is generally oval in shape. A torsion ring which is generally oval in shape completely surrounds the cavity and distributes the weight thereof around the perimeter of the cavity.

A set of iron-type golf clubs including a predetermined number of clubs, each club including a shaft and a club head, each club head comprising:
- a hosel portion;
- and
- a blade portion attached to said hosel portion;
- said blade portion comprising:
- a substantially planar face portion for striking a ball which is generally oval in shape;
- a back portion which is generally oval in shape and is disposed opposite said substantially planar face, said back portion including a cavity which is generally oval in shape, having an upper central portion and a lower central portion and includes a floor portion;
- a torsion ring which is generally oval in shape and completely surrounds said cavity and evenly distributes the weight thereof around said cavity;
- whereby the substantially planar face, upon striking a golf ball, will flex and distribute energy forces out to the torsion ring which will return the energy forces back to the substantially planar face to propel the golf ball from the substantially planar face.
A set of iron-type golf clubs including a predetermined number of clubs, each club including a shaft and a club head, each club head comprising:
- a hosel portion;
- and
- a blade portion attached to said hosel portion;
- said blade portion comprising:
- a substantially planar face portion for striking a ball which is generally oval in shape and having a toe portion, a heel portion, a top edge portion and a lower sole portion, said top edge portion forming a curved surface between said toe portion and said heel portion and said lower sole portion forming a curved surface between said toe portion and said heel portion;
- a back portion which is generally oval in shape and is disposed opposite said substantially planar face, said back portion including a cavity which is generally oval in shape, having an upper central portion and a lower central portion and includes a floor portion;
- a torsion ring which is generally oval in shape and completely surrounds said cavity and evenly distributes the weigh thereof around said cavity;
- whereby the substantially planar face, upon striking a golf ball, will flex and distribute energy forces out to the torsion ring which will return the energy forces back to the substantially planar face to propel the golf ball from the substantially planar face.
A set of iron-type golf clubs including a predetermined number of clubs, each club including a shaft and a club head, each club head comprising:
- a hosel portion;
- and
- a blade portion attached to said hosel portion;
- said blade portion comprising:
- a substantially planar face portion for striking a ball which is generally oval in shape and having a toe portion, a heel portion, a top edge portion and a lower sole portion, said top edge portion forming a curved surface between said toe portion and said heel portion and said lower sole portion forming a curved surface between said toe portion and said heel portion;
- a back portion which is generally oval in shape and is disposed opposite said substantially planar face, said back portion including a cavity which is generally oval in shape, having an upper central portion and a lower central portion and includes a floor portion;
- a torsion ring which is generally oval in shape and completely surrounds said cavity and evenly distributes the weight thereof around said cavity;
- a center of gravity;
- means for adjusting the location of the center of gravity of said club head, said means for adjusting comprises a cresent-shaped ledge positioned at the lower central portion of said cavity;
- whereby the substantially planar face upon striking a golf ball, will flex and distribute energy forces out to the torsion ring which will return the energy forces back to the substantially planar face to propel the golf ball from the substantially planar face.
