Runner’s “Keychain”
Jun 12th, 2018 at 9:07pm
 
This little guy is a solution to a very specific problem:

Several years ago, I was running with my dog, and three strays started harassing her and nipping at her heels. I was helpless to do much except run faster and attempt a kick once in a while to keep the stray dogs from landing a good chomp on her back legs.
I decided I needed a better way to keep the strays at bay if it ever happened again, and after a very unpleasant attempt at running with a steel baton,  followed by several prototypes and iterations of the monkey fist, I settled on this design as a solution for protecting Jules while jogging.
It weighs 111g, so it’s not too heavy to jog with. 80g of that is in the monkeys fist with a 1” steel ball inside. 
The whole thing wraps comfortably around the hand and holds my house key on the key ring while I run. I usually jog at night, and my other hand carries a flashlight that weighs ~90g, so I stay pretty well balanced.

It’s only half a meter or so long, but looks are deceiving. Pull the hitch pin that’s attached to the key ring and the paracord monkey chain unravels to reveal a 80g ball swinging at the end of about 1.5m of cord. Add my arm’s reach to that, and I can reach out further than my foot ever could without losing balance. Plus, it deploys really fast. Fortunately it’s never been necessary as anything but a key ring and a counterbalance to my flashlight.

It takes  some practice to control it. Very similar to a chain rope or perhaps a very short meteor hammer.

It needs a good name.

Monkeys fist with steel ball sounds like a good ammo for rabbits . Might need to learn that knot

It’ a great knot to learn, but it’s a lot of work for rabbit ammo. Why not just a steel ball? Are you wanting to avoid the bounciness of raw ball bearings?

Having done a few monkey fists and never really being able to do one as perfectly as I would like, I would also say just use the bearings as is.

Mine take well over an hour to put together on a good day. Once the basic knot is done, I work all the slack into an extra loop in the middle and hide the loose ends under the surface. It looks great, and I’ve even sold these keychain lanyards for about $20 each, but I stopped doing that because they take too much time to get them perfect. You can buy a monkeys fist online for way less than the price where I value my time, so now I only make these for friends once in a while.

I just might find it if there is a little cord tail

The tail is about 4 feet long when you pull the pin!  I guess you could try slinging it at a rabbit  Huh
