I would have to go with your guess bob, as it looks like it would cut the old copper braded seal wires on a gas or electric meter, and then mash the old lead seal disc with the anvil end of it, after installing a new wire seal.
Check this name again if you would, as I came up short with "isw.kucle"?
PS. It looks familiar, because Dad worked for the Pacific Gas, & Electric Company for 30 years.
