Overall the hammer is very good but the one I received has an irregular shaped head. It was tilted a few degrees. The problem is I didn't notice until I used it 2 days ago when I drove a nail into a bolt and left a moon shaped dent on the right side of the bolt. After several observations of this phenomenon, I looked closely at the face of the hammer and found that the face was tilted. Unfortunately, the deadline for returning the product has expired, so I could not return it. Now I'm stuck with a hammer that needs to be rotated a few degrees to the right so it's flush with the surface you're hammering on. The problem is that it creates a hot spot that is uncomfortable and can lead to blisters. I recommend buying hand tools from the store in person so you can get a feel for the tool and actually look at it. That way you won't be surprised when it's time to use it and if it is, you can at least exchange it for another at the store. Although I saved $5 at first, I now have to spend another $20 on another hammer. So basically I lost $15. That's the convenience of e-commerce for you. Somebody like my crooked hammer, let them take it for ten bucks.
