trap and crush the tails. Virtually all testers appear to only examine this knot in its mid-rotation state. It is theorized that this mid-rotation state is in fact the orientation where the structure is most vulnerable to capsizing. In addition, when tying the offset overhand bend using different rope diameters, the thinner diameter rope must be positioned underneath the larger diameter rope. This tactic further inhibits any likelihood of capsizing. The offset figure-eight bend, a similar knot using the figure-eight knot, has been used in the belief that its greater size and complexity brings more security. But testing and more than one fatal failure indicate the figure-eight variant to be less secure, more prone to capsize at lower loads, and in capsizing uses more of the ends than does a capsizing overhand bend. Moreover, while there is one proper dressing of the overhand bend, there are a couple of dressings for the offset figure eight bend.
