I am looking for any metal type, size, color, shape of scales to be made into leaf armor.

The scales must be at least 20 gauge or higher. Scales must also have a penny smoothness to the edge to prevent cutting the skin, for use in live combat.

I have looked online and the only place I could find was 3w.theringlord.com and the scales are to thin and to sharp.
Can anyone help me on this quest?
