Grapnel Line
this blaster-like tool was used to fire a filament cord at a target. The end of the cord was connected to a claw-tip that could dig into rock or metal, securing the line at the far end of the shot. The other end of the cord was secured to the gun itself, providing the user with a way to span short distances. The cord could also be used as a pendulum, with the user hanging onto the gun end and swinging across a chasm. When used this way, a button or switch could release the claw-tip from its hold, then the filament could be recoiled and used again later.
