Years ago I read an article in a tennis magazine that stated that if you lost ten pounds of body weight you would effectively be lessening the pounding on your knees by 5 G's (gravities). I don't recall all of the math and all of the reasoning behind the statement, but the moral of the story was that you could significantly improve the lifespan of your joints by going on a diet.

I would like to see the numbers behind the improved efficiency of the hammer. First off, I'm not certain that I believe 97% of the energy gets transferred. Is that only if you make the perfect strike on the head of the nail, or is that for your average strike? Also, what kind of usage would you need to get out of the hammer to make it worthwhile? In the years when your father swung a hammer on the job site I assume that pneumatic nail guns were not available. Today, would that money be better spent on a lighter wieght nail gun because you aren't likely to use the hammer enough to get a repetative motion injury?

All that said, I would still love to win one of your give-away hammers! :-)
