making a grappling hook ?
i know there are already instructables on grappling hooks but none are quite what i want . criteria are :strong,cheap, a good weight heavy enough to get distance on a throw but not so much that it feels like carrying round a rock , adaptable from tasks like getting up a tree to using as an anchor from a boat(which i plan to make at some point) to dragging logs around etc. i have an idea of welding together some heavy duty nails or screws. or possibly putting some screws into wood but im worried that the former would be quite difficult for me to make with m lack of experience and the latter to be to weak .so please could anyone reading this put there ideas forward ,
thanks wood wizard
