The very first time I used a hammer it came out of the rubber grip. Slipped back very easily but it's also very loose. I'll use one of the epoxy glues on it when I get back to that. Very dangerous as it can easily fly out of the rubber handle and hit someone or something and cause a lot of damage. As a professional I cannot recommend this hammer as the handle is not attached to the hammer handle. Spend more and get a famous brand. I should have stayed with Irwin.
