MashedThumbs

Speaking as a geologist, Obey gravity, its the law. All waterfront property is temporary. The only thing dumber than building on an ocean front cliff is building below sea level (does New Orleans come to mind).

You cite some very specific values for the difference between titanium and steel (A titanium hammer transfers 97% of your energy from swinging the hammer to the nail head, while a steel hammer transfers only 70% of your energy to the nail.); could you provide the source for those numbers? If this is from an independent source, that's one thing, if it is from the company selling the hammer, that's another. If I recall correctly, kinetic energy = 1/2 mass time velocity squared. And I suspect that energy transfer would be effected by the elasticity of the hammer face. Is there a materials engineer or physics type out there would like to weigh in with some facts?
