A golf club head is described having a body defining an interior cavity and comprising a heel portion, a toe portion, and a sole portion positioned at a bottom portion of the golf club head, and a crown positioned at a top portion. The body has a forward portion and a rearward portion. A non-metallic striking surface is positioned at the forward portion of the body.

An adjustable interchangeable golf club with a faceplate-based platform to receive components for enhancing and controlling various aspects that control the golf ball flight and spin characteristics. Disclosed are components for adjusting loft and bounce angle, and interchangeable faceplate and rear flange styles. Novel milled surface roughness for enhanced spin control is disclosed along with new milling methods for achieving optimal surface roughness. Lightweight hosel and consequent redistribution of mass in club head greatly increases the inertia of the golf club. Centrally located hosel position aids in club head stability on off-center hits. This results in a golf club that hits the ball higher, straighter, longer, and with increased ball spin characteristics.

Disclosed herein is a golf club head that comprises a body. The body comprises a sole portion, a crown portion, a skirt portion, and a face portion, positioned at a forward region of the golf club head, opposite a rearward region of the golf club head, and extending from a toe region to a heel region of the golf club head. At least a portion of the body is made of a titanium alloy. The golf club head also comprises a large weight, coupled to the sole portion of the body and made of a steel alloy. A mass of the large weight is at least 40% of a mass of the portion of the body made of the titanium alloy. A total mass of the large weight and the portion of the body made of the titanium alloy is at least 210 grams.
