The mystery object lying on the floor, is a very special tool; The Burndy Connector Gripper : )
Anyone with a little arthritis in their hands, and having the occasional job of loosening rather tightly clamped up Burndy [or bunch of them] may want to own one of these very special and specialist tools.
An excellent investment made few years ago from Tesco for 99p
It will, however, need some modification with a sharp tool, the gripper needs an open aspect rather than enclosed in a loop. The thing is made from soft rubber so is harmless to the connector but allows one better purchase grip [just for the little bit of initial turning] with no loss of skin from finger tips.
Was thinking of buying a hundred of them, cutting them down to size, and re-marketing them as a patent Nymph Industries Burndy Connector Loosening Tool: price $99.99 available while stocks last.
TBH i'm very capable of removing tight fitting jar lids, but don't ask me to undo a tight@$$ burndy cable connector
