Figure Eight Table Set 4

Unusual and Special Purpose Eights

Table 13: Bent, Odd Shaped Rope Hole Eights

All of these eights are bent (they will not lie flat) so they have two different rigging configurations that provide different friction.
None of these has a round or oval rope hole.
In this table, special shading in the ID field background indicates eights that are particularly similar except for markings and possibly finish.
