I have problems agreeing with the myth busters. I have been working with hand tools (including hammers, chisels, and punches) for over 40 years and have had several hardened items chip or fly apart when being struck.I worked in a heavy equipment repair facility and we commonly used two 16 pound sledge hammers to free frozen gears or items pressed together with up to 200 tons of pressure. One hammer was held on the frozen part and then struck with the second hammer. Not only have i seen chips fly out from the hardened surfaces of either hammer, but more importantly numerous hammer handles came loose due to the hole in the hammer head being deformed when struck by another hammer.
