I didn't think you could screw a hammer, but these guys could. The metal is soft as butter, use once, and the tip is full of space, and the whole face is wrinkled. Most of my tools are Harbor Freight so I wasn't expecting a super awesome tool but this is the worst hammer I've ever used. All of my Harbor Freight hammers are at least hard enough to last a long time. But this part is just useless after one or two uses. Avoid at all costs
