At first it looks like something for a torch, but at second look maybe it fits on a pole and is used in line work. What do you think ?
The second piece is a Challenger 1016 by Penens and is a 1/2 socket with 1/4 drive on top of plastic knob. Just a curiosity I hadn't seen.
I got it in a box of tools I paid way too much for to get the third tool which is a Buffum Tool Co cotter tool.

The hook thing is a high voltage line fuse puller and closer installed on a "hot stick"  an 8-10 foot non-conductive pole.

Bruce S is kinda almost right, except the Bell Companies dont ever touch any high voltage or fuses. We do use that hook on poles to install drop wires and the poles accept a saw to cut brush and  limbs

Thanks Jimwrench! I just got a KeenCutter cotter tool and wondered what it was. Hadn't got around to posting pictures but now I know.

The Royal Signal (British Army) use a similar tool to the Bell Systems one when laying telephone lines - military prefer old fashioned telephone to radio whenever possible - less easy to hack into, less distortion, thus more secure.... Whenever possible phone lines are hung in trees, placed in hedges or on fence lines to avoid damage by vehicles...

they make fantastic weapons

I think Bob wins for 'shortest hotstick in existance' LOL

Somewhere I saw that shape referred to as 'wire lifter and tree hook', which would make sense for a Bell tool. The phone guys have their own tree nightmares to deal with ...

especially when they work poles alone.  bob w.

Pushup pole end minus 5 feet of wood
Can wrench for splice cans
Damned if I know what the 3rd one is
