Call it a headless hammer or simply a sleek dead blow striking tool. Some of us call it a bopper or a basher. Regardless of the name, the dead blow extender is indispensable for striking areas that are unreachable using a hammer. You can swing it, you can pound on it with a hammer, and you’ll always get the results you want. Two different diameters on the ends add to the versatility of this unique striking tool.
