The first time I used this hammer it hit my thumb. If you decide to buy this be careful it will hit you on the thumb too. So you think I just hit my thumb with a hammer? Have you ever seen a baseball player throw a ball and look down at his glove? Because the glove was to blame. The same applies here. The hammer is to blame. Stupid Hammer. Otherwise it would be a good idea to buy a rubber mallet. You might get one that doesn't hit the thumbs.
