Club heads with varying impact responses and related methods

A method of providing a golf club head, the method comprising:

• providing a strikeface of the golf club head;
• and
• providing a rear body of the golf club head;
• wherein:
• the golf club head comprises:
• a top end and a bottom end opposite the top end;
• a front end and a rear end opposite the front end;
• and
• a toe end and a heel end opposite the toe end;
• providing the strikeface comprises:
• providing a striking surface;
• and
• providing a rear surface opposite and rearward of the striking surface;
• providing the rear body comprises:
• providing an internal front surface;
• and
• providing multiple protrusions;
• each protrusion of the multiple protrusions comprises a first end and a second end opposite the first end;
• the first end of each protrusion of the multiple protrusions is coupled only to the rear surface of the strikeface and extends away from the strikeface toward the rear body;
• wherein each protrusion of the multiple protrusions has a length measured as the distance from the first end of each protrusion to the second end of each protrusion;
• wherein each protrusion of the multiple protrusions comprises a solid slat;
• wherein the strikeface comprises a strikeface material selected from the group consisting of:
• steel, stainless steel, steel alloys, chrome-plated steel, tungsten, beryllium nickel, beryllium titanium, and titanium alloys;
• wherein the multiple protrusions comprise the strikeface material:
• wherein each of the solid slats has a width dimension measured laterally from the toe end to the heel end of the golf club head;
• wherein each of the solid slats has a thickness dimension orthogonal to the width dimension;
• and
• the golf club head is configured such that:
• when the striking surface impacts a golf ball with a first amount of force, the multiple protrusions deflect toward the strikeface with a first amount of deflection and the multiple protrusions extend towards the internal front surface of the rear body.
