Do you break down copper transformers?

That way there's no overheads in discs and its a cold cut so the plastic insulation falls off easy.

Though a angle grinder and cutoff disc is quicker. The way a sharp chisel cuts thru Copper wire is quite therapeutic.

I agree the wood chisel works really good, if I'm using the air chisel I sharpen the chisel being used with the same profile as the one used for wood.
