Scissors that went to the gym and started cutting metal for fun.

means A hand tool shaped like heavy-duty scissors, used for cutting sheet metal, thin wire, and ductwork.

from Straightforward compound: 'tin' for the thin sheet metal (originally tin-plated steel) it was made to cut, and 'snip,' a word from the 1500s imitating the quick, small sound of a shearing cut. 'Tin snips' simply named the tool by its material and its action — no hidden story, just plain, honest English.
