This is one of the first knots that i learned and has been a lot of fun to teach friends because it is very simple and anyone can do it.
The handcuff knot i am about to show you can be used for many things like playing around and joking.
I do not not suggest you use this to tie up a actual criminal and am not responsible for what happens if you do so.
Step 1: Materials
For this knot, all you need is about 2" of Paracord. (size varies by person)
I used about that for this project
Step 2: Make Your Bites
Next you need to flip one part of the rope behind and one over in front. to create two small bites
Step 3: Pass Bites Over
Next, on the right bite.
Pass the side closest to the left bite over top of it so that the right bite lays on top of the left.
Step 4: Pull Bites Through
Next, pass the right bite under the left and the left over the right.
Easier seen then explained, see video for better visual
Step 5: Pull Tight
To pull the knot tight, pull on the upper parts of the bites.
To make the holes bigger for hands to go through, pull on the lower.
Pull on the strings coming from the bottom to tighten.
If nothing is in the loops and you pull on the strings, The knot will release itself.
Step 6: Video
This is a Personal video i made to help show it
i found this video that does a great way of explaining it
