What Martinez hammer is right for me

Some of the smooth faces have been powder coated black. You may find that the powder coat will chip. This will not affect the performance of the hammer in any way however, if you are concerned about it, you can safely sand off the powder coat with a sander to reveal the smooth steel face.

Once assembled the item is non returnable
