Yeah,
It's marvelous to watch a skilled operator and his machine in action. Honking great chisel located with precision on a rusty bolt head and --- Wham, all done.
Similar thing, I watched the tiler putting tiles on our kitchen wall some years back. It was as though he was dealing cards, job done, straight lines and equal spacing without any gizmos to aid. Just stood back every so often, looked, and if necessary nudged the odd tile into line.
Me, I would still be trying to get them right.
