1. A metal wood golf club head comprising, a crown portion and a sole portion, a toe portion, a heel portion, a ball striking surface extending between said toe portion and said heel portion and between said crown portion and said sole portion, said ball striking surface having a lower marginal edge intersecting said sole portion and extending from said toe portion to said heel portion, said ball striking surface also having an upper marginal edge intersecting said crown portion and extending from said toe portion to said heel portion, a hosel extending from said crown portion at the location where said upper marginal edge joins said heel portion, said hosel having an opening extending therethrough along an axis disposed adjacent said ball striking surface at said heel portion, said crown portion and said sole portion being joined together along a common outer margin to define an edge at said common outer margin, said crown portion defining a continuous curve from said marginal edge to said common outer margin, said crown portion also defining a continuous curve from said heel portion to said common outer margin at said toe portion, said lower marginal edge of said ball striking surface defining a continuous downwardly extending generally convex curve from said toe portion to said heel portion so that at approximately the mid-point along said convex curve, the vertical distance along said ball striking surface from said lower marginal edge to a horizontal line extending between the toe portion and the heel portion of said lower marginal edge is at least twenty percent of the vertical distance along said ball striking surface from said mid-point of said lower marginal edge to said upper marginal edge.

Abstract
A metal wood golf club formed without side walls wherein the crown shares a common outer margin with the sole so that side wall portions are eliminated. The ball striking surface has a marginal edge within a portion of the common outer margin. The hosel extends from the crown adjacent the ball striking surface to a level near an upper extremity of the crown. The metal wood golf club may be formed with a cast forged or molded shell having a hollow interior, the sole and portions of the crown adjacent the common outer margin having a selected thickness and an upper portion of the crown extending from the common margin has a reduced thickness.
