Introduction: DIY Grappling Hook for Under $5

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

Step 1:

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.

Step 2:

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

Step 3:

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.

Step 4:

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!

thank you for your concern, yyrkoon1965, but this grappling hook does have the ability to lift quite heavy loads. here is a picture of it supporting me

I would not have believed that your hook would support you, but there is your picture. Good job.

However, I think I agree with yyrkoon that it is not a good idea to use it for "life support" (as they say).

I am worried about a number of elements. Can you show a picture of how the hook looked after it held your weight?

a) did the metal hooks bend under your weight?

b) did the surgical tubing slip at all?

c) did the knotted paracord slip into the tubing, past the hose clamp?

d) did the duct tape show signs of tearing or slipping?

along with no surgical tubing or paracord slippage

as you can see, the duct tape has not ripped and the hooks are unbent

Static loads versus shock loads.

I just don't want someone getting hurt.

DO NOT USE THIS FOR SUPPORTING LOADS, IT IS NOT SAFE!!!!

Good job on the instructable but it should be used for gear retrieval only!

I'm not sure if you have tested this, but it doesn't seem as if it can support a serious load.

When I was younger I was using a grappling hook a friend had made out of welded rebar, it gave out and I slid over 100 feet down a cliff face.

Safety first.

Good job, this turned out really neat! Oh, the diagrams were clear too, I have seen some that were pretty bad.
