In many municipalities this is known as a fistload or blackjack.Many think of a blackjack as being made of leather but many were made of cordage.They are very illeagle most any where you go.
Kevin,I really like to see a young person taking up knot work.When I was a young sailor,knotwork and splicing was a favorite pass time.It is nearly a lost art.YOU DO BEAUTIFUL WORK!
I recommend "The Ashley's Book of Knots" by Clifford W. Ashley.You will love it...
