I'm going to raise the point again that items picked up off the ground pierced the Gods flesh.
Regardless of the Titan's strength the items should have splintered on impact considering the arguments of Poseidon withstanding the impact damage required to create the tidal wave.
The Titans used random metal rods, hammers and scimitars.
Superman withstood in his first flight smashing through a mountain at high speeds. And his abilities increased alongside his Kryptonian adversaries as the film continued.
His flight and eye beams will cut them in twain. His attacks would punch eviscerate them and his durability won't be compromised by random items found on the field.
