My event

I have a couple of questions about an event I want to make.
(1)
It involves the main character hunting for dragons.Once he has killed the dragons he receives Dragon scales.Different colored dragons have different scales.After the scales are acquired I need to be able to take them to a blacksmith.The blacksmith then converts the scales into weapon or armor.The different colored scales make different items.For example,if I take the blue scales to the blacksmith he wil make a water enchanted sword.Yet if I take the black scales he will make a Death inflicting axe and so on.
(2)
The second question is how to make the black smith once he has recieved the scales go to his anvil pull out a hammer and appear to be working on something.(I already know how to make him go to the anvil just not how to pull out hammer and make item).
