/diy/ - Do It Yourself

>>1491390
I located a place where i can buy 1mm (19 gauge) stainless steel sheets, but i have to concerns:
1. They have the common one (pic) and a darkish one
2. I want to make eternal fantasy and historic armors (like the ones from 40k and from classic civilizations), which one should i pick?
3. What kind of coating do i have to buy?
4. I will use a hammer, but what kind of tools do i need? what kind of cutters?
5. Do i have to heat the steel for a few seconds? (i saw that method in another blacksmithing thread)
Help please
