SG Replacement HAMMERSTRIKE Shell, Inside/Straight

STANDARD GOLF HAMMERSTRIKE Replacement Shells

• Hammerstrike cup shells are heat treated to reach 60 on the HRC scale.
• This environmentally friendly method creates a sharp cut with excellent edge retention and the ability to hold a very sharp, precise edge for a long time.
• Heat treating is not a coating, so no surface putting, flaking, or hydrogen embrittlement.
• INSIDE sharpened/straight shell (for sand-based green)
• size: 4.25''
