I’ve used the hot stick (switch hook) inside of substations on rare occasions, though my job was more to deal with the secondary control circuits than to do primary voltage switching. The end of the hot stick has a little peg that fits into that eye and operates the latching mechanism that allows you to open (turn off) or close a switch of fused disconnecting switch. Lots of those on the tops of poles.
Here’s a little video where a lineman has replaced the fuse cartridges and is attempting to energize a circuit (presumably a transformer) that still has a fault condition. First fuse goes in fine, but when the lineman completes the circuit, you can see the first fuse blows and swings open, as designed...

NICE dunk on the knowledge CDY!ðŸ¤
The only problem that I see in this picture is that neutral / ground wire on the top. That presents a very dangerous hazard in storm conditions. That should run underneath the 'Hot' lead, generally 7,000 or 14,000 volts. In my area it runs that way.🤔
