Copper scaled MOD Spartan

One more material to add to the list....  I used a grinding wheel this time to speed up the grinding process, but after every minute I had to stop grinding because of the friction-heat. Red copper is super conductive and it shows after a few blisters... When it comes to engraving, it is a far easier material. I don't like the colour and after polishing it becomes real hard to see the engravement, but must say that it has something special....
