I noticed a small rusty puce of metal in a parking lot yesterday and it just looked cool. I sanded one side smooth and made a necklace pendant for my grandson, Ryder. I used some mystery blades that came with my saw. I just sprayed a little clear coat on it and left the front side as is. He loves it. Wish I knew what the chunk of metal was.
***Did some looking and it’s a 25 gram steel adhesive tire weight
