The Shamir is worm, or a substance, that had the power to cut through or disintegrate stone, iron, and diamond.
It was used by King Solomon in the building of the First Temple in Jerusalem in the place of cutting tools. For the building of the Temple, which promotes peace, it was inappropriate to use tools that could also cause war and bloodshed.
In the video game Beast of the Fifth Sun in the final level, Weird World, they remade any stone blocks destroyed by a variety of things throughout the level, mostly traps and other cryptids, and attempted to encase Zak in stone more often than not.
