What is your RAREST collector item?

[underfox]

in all honesty I don't plan to make it my self. If I ever finish it, I think I'll buy a miniature katana on the net or I could ask a friend of mine to do it for me.

I don't have the required skill to work with metal and I can't scult it with clay as it would be way too fragile without breaking the following day while drying.
