but why do it the easy way?

The easy way to detach an item from a rope you can't reach is to set the rope on fire.

The stupid - but possible - way is to glue multiple items together until you can manage to glue an air vent at an angle to blow a steel spike at the rope and destroy it. Hopefully without destroying everything else in the process. (Steel is indestructible and anything else can be destroyed by spike impact, pretty much...)
