I haven't swung them at anything solid just yet, but just threw them in the yard. The KDH is surprisingly light. It is shorter, thinner, and has less material at the head. Reminds me of a 10 in hammer in weight. Very easy to throw. Neither feels very head heavy. The Rattlehawk is definitely heftier though. I'll have to let you know more, when I put them to use. I'll go to the clubhouse this weekend and see.
