I (14m) have started metal working because I want to make some sort of armor for fun. I have been using a scrap hammer I found in a pile of rusted iron for shaping sheet metal I have found in the yard, I was wondering if this is okay over time. (I do not own an anvil, forge, or any metal working tools besides this hammer, and have been making any equipment I need by hand, including the handle for said hammer, which I made from an old branch.)
