*As of May 2019, some GHP handles have changed slightly. Knurling is slightly more smooth overall and only 1 handle has a sticker. The other handle has a "GHP" brand stamp.
Gillingham High Performance assembles grippers in small batches with strict quality control to ensure consistency at every level. GHP grippers were designed with variable knurling for a unique feel. The palm-side knurling is slightly sharper than the finger side to help the gripper seat in your hand.
