Hi Viz Green - The Spool Tool is the all-in-one answer to storing and working paracord. This simple little device holds up to 100' of 550 paracord and features everything you need to measure, cut, and heat-seal the ends. No more tangled line, no more missing tools, and no more melted globs burning your finger tips and sticking to your gear. The Spool Tool is molded from glass-filled nylon for strength, lightness and durability. The replaceable blade is the best available: Lenox's patented, shatter-proof, bi-metal alloy with titanium-coated edge. The Spool Tool can also securely hold a mini BIC lighter (not included) for heat-sealing paracord. At 6" long, 3" wide, and just over 1/4" thick, the Spool Tool is small enough to carry in a cargo pocket or backpack pouch. The Spool Tool comes with a lifetime guarantee and is MADE IN THE USA!
