As Idoru correctly stated, asking in game is the way to go, but allow me to add just a bit to that. Right now, as Neko said, crafting, including producing weapons, is undergoing some upgrades and is not working at the moment, but should be back up and running soon. When it is, look for someone at a smithy shop working at the forge or anvil to ask. As alway, tis always best 'to roleplay for it." For example:
okay:
Newcomer: How do I make a sword?
Master Craftsman: Well, first you make a blade, and then you make a handle for it, and then see, you assemble the two together.
better:
Newcomer: How can I learn to make a sword?
Master Craftsman: You need to train and get the right knowledge from the smithy first, then maybe you should join a guild and they can teach you the rest of what you need to know.
Best:
Newcomer: Excuse me, Sir Dwarf, but I've sought the needed training to begin making swords, but need a bit more tutoring to learn the art. It would be both an honor and a privledge if someone as skilled as you would be so kind as to tutor an eager and willing apprentice, such as myself. a bit, so that I might better understand how to make a basic sword.
Master Craftsman: Err, sure, it has been a while since someone as worthy as yourself has approached me for such tutelage. I'd be happy to show you a bit.
It won't work every time, but your odds of getting a decent answer will improve dramatically.
G'luck
