Monkey Fist Self Defense Keychain 1" Steel Ball Double Line 550lb Tensile Strength Military Paracord (Length 6 5/8") by Muzitao©

So, I had never heard of a "Monkey Fist" until very recently. But, once I saw one I got the idea immediately. Hold the key ring in your hand and swing the little ball end at a bad guy until he goes away.

Once I got mine in the mail I decided to go on the internet and quickly found a number of videos that demonstrate the effectiveness of this self-defense tool. The videos showed me two things: 1) There are some really freaky guys out there making self-defense videos and 2) this monkey fist thing can do some real damage. I saw watermelons split open and dry wall mangled. I also saw one guy insist on putting the key ring around his finger. I would not do that - if your opponent were to grab the monkey fist he could pull on it and really do some damage to your finger.

Instead, put your keys on this thing and hold on to the entire collection of keys in your fist and swing away.

Note: on those videos I saw much longer cords being used. After thinking about it I think a longer cord would be of use only if your opponent was pretty far away. If you are grappling with someone, a longer cord would require more swing and more arm movement that you may be able to actually come up with.

So, how high of quality is this product? I have no idea how long this would last if it were used repeatedly. But, then again, who is regularly getting into fist fights? And, if you do get into tons of fights this Monkey Fist is cheap enough that you can buy another one without breaking the budget. By the way, these come in 11 different color schemes.

Note: I received a Monkey Fist for free in exchange for an honest review.

I rate this product 5 stars out of 5.
