The estwing is a good tool.I own a black eagle as well as a double bit estwing. I really should put them to the test out at the farm, at least hack up some brush or clear a few lighter limbs along some trails. The double bit is a sharp bugger and just feels dangerous. I could see myself wildly swinging it back and forth in a sea of zombies. Hopefully it never comes to that. Lol.
I've abused mine a lot and it's holding up very well.
