Please note that the Filing Service permanently alters the gripper. Grippers are always filed first, then rated. Our custom filing process leaves a beautiful finish on the cut surface of the gripper handle.

If not all the grippers on your order will be filed/rated then you can specify which gripper to file/rate in the notes at checkout. You can also specify which color tag goes with each gripper if multiple colors were ordered. Email if you have questions.


Grippers in a sealed package (IronMind, GHP) must be opened for the rating and filing service.  You will still receive the packaging with your gripper.
