Well darn I just ran out of rope and I need to get across this huge gap my techs won't get me far enough so, pull out your fishing rod device, hook it on to the nearest surface and, swing across. It would be really useful and fun and besides, that thing is reinforced with TITANIUM so I don't think it would break too easy.
There is already a grabbing hook in the game but you you need to upgrade your crafting stations to unlock it.
Everything is allowed to be suggested, doesn't mean everyone will agree with it. As someone mentioned, there is already a grappling hook in the game which does what you're suggesting. Therefore to add it because it's funny, isn't that great of an argument to have it be implemented.
I think its cheeky, and would really be an interesting hidden use for an item with so little versatility. besides I think cleverness should be rewarded.
