To utilise your cord in an emergency simply untie the overhand knot on the end of your cord.
Undo the loops around the buckle ( keep the buckle for attracting attention)
Pull the length of cord back through the first 4 loops to release your working end
Pull hard on the working end and the whole belt will begin to unravel. From start to finish you can undo the entire belt in about 20 seconds (a painful thought when you realise how long it took to make)
Alternatively if you have a knife or a pair of scissors simply cut where shown, remove the end with the buckle and pull on the cord you cut to unravel.
Dont forget to use your emergency whistle to attract help if you need it!
Paracord is fantastic stuff but its no substitute for another pair of helping hands!
