29. Directional Figure 8 Loop

Also known as: Inline 8

Tied on a bight, the Directional Figure 8 Loop is meant to bear weight in
one direction only. In this role it excels and is favored by climbers. Beware
of applying weight in the other direction, however, for the knot will capsize
and slide, functioning as an unintentional noose.

Uses: climbing, lifting, load bearing
Pros: easily tied; very strong

Cons: will slip if load is applied in the wrong direction; dangerous to careless users; difficult to untie if
tightened hard
