The Estwings balance and handle like a hammer. I love my tomahawk and double bit, but there is no getting around the fact that they are made like a hand tool.
For that reason, I didn't go to the extra expense or maintenance effort of leather. Rubber grips work just fine. I have been abusing mine for a few years now. Besides some scuffed paint, they are holding up well. The handles are dirty but look brand new otherwise.
