9,10,11 & 12:
Open this newly found "loop" as wide as need be. Slip your entire hand through the loop. Position the knife and cinch the loop tightly around your wrist. I have large hands, wrists and arms and the wrist thong that comes directly from the Randall shop is plenty long enough for me to achieve this method and grip/hold. If, for some reason it doesn't work for you, get a longer piece of paracord and start over. (But make sure the tag ends are pointed away from each other during each and every stage of this knot!)
