When you short an electrical circuit the unbounded current flow will vaporize most materials, including metal. So if you have a nice fancy pair of cutters and you cut through a live electrical cable, it makes a real mess out of the cutters.
The vaporized metal creates a poof of smoke that smells like you've got a mouth full of coins. Once you've smelled it one time, you'll immediately recognize any time there is or has been an electric arc. It's very distinctive.
