| | |  Rusty iron plate. Just some old iron pulled from a junk pile at the farm.  The sound is steel plate like this being beaten with a blacksmith's hammer.
 See hafnium for some pictures of a plasma-arc cutting torch cutting some steel plate much like this, and see oxygen for a story about how oxyacetylene cutting torches actually work.
