It is used for disassembling a solid road block with stacked rebar with four corners. As a 4 kg hammer, it was cheaper than other products and purchased with expectation for durability of the handle. It is good to make it solid. I hit it for half a day, but it did not happen. Since the buttocks are rubber wraps, they do not have to slide.
Although I have been using wooden large hammer for several decades, I was in trouble because I broke the branch many times with new employee, so I bought a branch of a glass fiber saying that it will not break with some things I bought it but gave it but it is not broken yet. I am using it as a test, but I think it's pretty good. 3 It seems that it will last as long as it is diffracted and lasts longer.
