The i4-TECH Rachel is a professionally crafted classically shaped cavity-back blade with a full shaft offset. All i4-TECH Putters have the new four-layer C-GROOVE insert that provides a smooth roll towards the target and improves consistency. Coupled with a soft feel it is tungsten weighted at the heel and toe to maximize MOI for unmatched accuracy and forgiveness. Don't let the antique finish fool you even though it has a classic appearance it features the newest technology in the putter category. What separates this putter from the Callie is the smooth curve in the hosel.
