This is probably one of the cooler yet underrated ama's of recent.

With non spark tools, say a common wrench, what type of metals are they using that are different from your ordinary say box wrench or Craftsman or snap-on tool?

Copper and titanium somehow now mix as an alloy? I'm not sure of the metalogical practices involves here but you have a very very soft pliable metal and then you got extremely hard yet fragile metal. Any ideas?

Even though you're right, they still downvote you...
