A light weight compact grappling hook which finds use in at least urban terrain comprising a small head member provided with a plurality of arms or blades which are serrated and/or provided with cutting surfaces/edges. The shaft which is connected to the head can be rigid or flexible. The flexible feature facilitates achieving a hold on surfaces which might otherwise be difficult. The arms or blades are each pivotally supported on pairs of pins and can be spread from folded storage positions and locked in position prior to deployment, or can be spring biased so that spreading and operative deployment is achieved en route to the target.
