Sword in the stone

One of the most famous objects of the King Arthur stories, must be the ‘Sword in the Stone'. The legend says that the sword was put in a stone and that the guy who could put it out, would be the new king of Britain. If you look at it in a realistic way, it just can't be real. There is no such thing as a sword that can be pulled out by the best man, at least not with the knowledge of physical laws.

Yet, lots of historians do believe that there was a historical basis for the sword in the stone. Back in de dark ages, people knew how to make metal. The only way a blacksmith could make a sword, was by putting melted metal in a template. Literally speaking, you pull the sword (once it has hardened) out of the stone1.
