I just bought another 5 pounds of wootz.
That will go nicely along the 20 pounds or so that I already have, the modern and antique tamahagane, the mosaic damascus, and normal damascus.
:p
My 'sickness' is steel. Although I will say that the main reason I buy more steel when I can is a) to anticipate on when I need it and how long I need to wait to get it, and b) I have it to be able to use it for custom orders without having to wait months (sometimes) for the steel. It's all in my inventory.
