This is a simple grappling hook that I made back in 7th grade and has turned out to be a very versatile tool. it is very simple to make and can be a great project for a long afternoon. it took a bit of prototyping for me to settle on this design but now that it is made, ill tell you how to do it in under 30 minutes.
Here is what you will need:
1. 15 feet of Paracord (or any thin rope that can support your weight)
2. 4 1' by 1/8" iron rods
3. a small hose clamp
4. 1 foot surgical tubing
5. duct tape
First, take the four iron rods and bend them at a 90° angle five inches up the rod, and again on the other side, except only two inches up the rod so it is in the shape of a hook.
Second, cut two 4" pieces of surgical tubing, and insert two of the bent metal rods in each cut piece of tubing so that the longer bent side is in the tubing. this is so the hooks don't slip
Third, tie a knot at the end of the Paracord, and use the small hose clamp to secure the rope and the bent metal rods together.
Last, use duct tape to hold the rope down on the end of the hook, and to keep the hook from bending.
There you go! you now have your very own grappling hook to swing into action with, and without spending more than $5!
