16oz IS one pound,
5160H won't rust too fast, and I could do you one for $350 in this, plus shipping to where ever you are, Assuming its legal to send it to you there. You did not state where you are.
I won't bother with the holes as they will only add places to hold moisture and cause rust, I do warranty my work.
I don't do Stainless, Making this out of stainless isn't the real trouble, as much as heat treat for stainless that will hold an edge will add a hundred or more to the cost, plus the cost of good blade quality SS would make this a very high dollar blade.
