I have over 50 years of experience in the construction and carpentry trades I bought this as a cheap spare hammer for a project away from home so I don't have to bring everyone my tools with me. The hammer has a surface and angle that will bend even a #6 nail. Bad design. Unlike the classic Craftsman hammers which were very comfortable to use. Bought 12 ounces. Estwing, great hammer, but more expensive. This is with my 24 oz. frame with a hammer and I'm fine for the rest of the job.
