They were dicks to me FIRST, assbrain. I give as good as I get, and then some. So, here's yours:
Do a barrel roll and drown in spurting pearl jam.
Now, back to the topic. What did you mean by "metal"? Do you mean:
1. Elemental metal.
2. Alloyed metal.
If #1 was your aim, then the answer is Chromium, at 8.5 on the Mohs scale.
If #2 is your aim, then the answer is Alloy 1090 of carbon steel. Note that that's still softer than diamond (which is the hardest substance known).
