The USA made Sungold Scissor Pressure Regulator will restore the blade camber to factory specs safely without damaging or marking the blades. Adjusting the camber with a hammer and an anvil is dangerous since it can both mark the blades with hammer dings and run the risk of breaking the blade. Only a custom pressure regulator tool can safely make this critical adjustment. For more information visit our website https://www.sungold-group.com/
