Fishing Line
The fish and fire cord also has a 8 lb monofilament fishing line inside the sheath. It can be pulled out of whatever length of cord you have cut. The monofilament fishing line holds knots well and is flexible. This type of fishing line has some stretch to it and is more forgiving than a static fishing line. It is also a little larger or thicker and resists abrasion along with making a better fishing line than the nylon inner core strands.
Fire Cord
Another item included in the sheath of the fish and fire cord is a strand of natural jute. The jute is purposely not coated with addition fire accelerants. It is a safe every day carry item. Jute is a fibrous material and can be used as tinder help start a fire. If the natural jute gets wet it will dry quickly and be ready for use.
