*GHP handles have multiple iterations which include both rounded and angled bevels. Generally there is an identification sticker on one handle and either a GHP brand stamp on the other, or a "made in USA" sticker.
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.
