What is the anvil for? Does it require an object? Can it be used to forge some weapon?

I'm talking about the anvil in Shurugeon castle which is in the room which leads into the room with the skeleton you have to kill to open (the door of).

Thanks in advance.

Sorry about the double post. My browser failed me (Will no one rid me of this meddlesome browser).

I tried to find a use for the Anvil too.. (like I thought that I would have to FIX the broken pull chain)... alas, I never found a way to use it (I tried).. if anyone else did.. I'd like to know what it was also.
