I'm hoping this hasn't been asked a lot before. But I am hoping to get into high end kitchen utensils. I want to be able to make spatulas, ladles, coffee scoops and the like, with copper working ends. I would love to skip some expensive trial and error on what a good gage of copper sheet to start with is for utensil making. Any help would be greatly appreciated. 

I think this is a question that I can actually answer. My store bought stainless steel spoon for mixing juice is around 20 gauge. I made some stainless steel spoons and spatulas several years ago out of 16 gauge. Several people have mentioned that they would rather use my homemade utensils over the store bought because they can really lean on them without them bending. Heavier gauge will make your utensils standout from the crowd.
