One of the factors that is being missed here is energy. When a hammer is swung, it contains a lot of kenetic energy, that's what makes a hammer effective. If you hit two hammers together, that energy has to go somewhere. Some of it will be transferred to the kenetic energy of the rebounding hammer heads and the remainder will be used in distorting the steel in the heads and will eventually wind up as heat. Given enough energy, you will distroy anything! Just look at the kenetic energy anti-tank weapons.
