Boatswain's Handcuffs - How to Tie These Self Securing PrusikKnot-Based Paracord 550 Cord Restraints

Earlier this evening I received this tweet https://twitter.com/knoxrover/status/317399362164649985 from @knoxrover asking if I was familiar with Boatswain's Handcuffs. I knew of this style: http://en.wikipedia.org/wiki/Handcuff_knot, but after he tweeted the photo (below), I realized this was something different. Looking at it I saw it was based on a Prusik knot. With a minute and about 4' of paracord, I was able to reverse engineer the knot.

First, tie the Prusik Knot around your finger, as shown or optionally with an additional pass.

Second, take each working end and insert through the Prusik Knot.
Finally remove from finger and work the Prusik tight. The paracord handcuffs are ready to use. Simple place hands in loops. Pull ends to tighten. The nature of the Prusik Knot is such that attempts to pull hands apart will only tighten the knot's grip.

A gentle reminder my #NH friends! Two springs ago my family and neighbors were greeted mid-day by a black bear family at the school bus stop!

How do you estimate the amount of 550 cord needed for a paracord project?

There is no magic answer to a most often asked question - "How much paracord do you need to make X". Two people will even use different lengths on the same project or knot. That said, you can keep your own data to help with the planning of new projects. Every time you do a new knot, or new size like a monkeys fist, measure cord before starting. Measure the remaining cord after. Keep this note so next time you can start with less and minimize waste.

For braids and weaves, make around 3" of a finished braid. Knot as you would if you were making it for "real". Mark the cord. Unravel and measure. Divide the amount used by 3 to get the length of cord per finished inch required for that braid. Don't forget to include the lengths of inner cords if there are any. Use this number as a multiplier next time you do a longer project to estimate required cord.

Always round up - better to cut excess than not have enough to work with. When planning a project with multiple knots and braids, refer to your notes for the individual knots and braids then add it all up!
