Abstract: A new and innovative method of routing a strand of material for creating a self-locking construct that joins two objects is provided. More specifically, the provided routing method includes a crossover point at which the routed strand of material crosses over itself thereby enabling the strand portions routed through one of the objects to travel in a same direction when the self-locking construct is cinched. The strand portions traveling in the same direction generates less friction between the potions than if the portions traveled in opposite directions. Accordingly, the provided routing method helps enable a self-locking construct that generates less friction than typical self-locking constructs, which thereby helps reduce the occurrences of weaknesses in the final self-locking construct. The reduced friction generation also helps increase an ease of use for a user when cinching the self-locking construct.
