"81's" are a bit of telecomms folklore ! They have narrow pointed jaws, specifically for wiring. The name comes from pre-war GPO stores descriptions, where they were described as "Tools no. 81". Later known as "Pliers, Wiring No.2".
The name 81s has stuck, at least amongst the older hands, and it is often recognised in BT, Royal Mail engineering, Royal Signals, and other government-related outfits. A bit like the Masons' handshake, I think !
