Here is a super cool, super handy belt that could potentially save your life some day. It's easy to make, and only requires the 550 paracord, and time. If you have hands that work, you can make this.
Having one of these wrapped around your waist means always having a strong, light rope that is around 120 feet in length. That is a serious length of rope. This could come in handy when you really need it.
