Description
The Offset Figure Eight Bend is simply a Figure Eight Knot tied in two ropes that have been doubled up. This 'Abnormal' Figure-Eight Bend and is inferior to the 'Normal' Figure Eight Bend. The Offset Figure Eight Bend has been implicated in the deaths of several rock climbers. The knot may capsize (invert) under load and this can happen repeatedly. Each inversion reduces the lengths of the tails and eventually the knot comes undone. When used at all, both ropes should be of the same diameter.
Structure
The Offset Figure Eight Bend will have working ends exiting the same side next to each other as opposed to a proper Figure Eight Bend where the working ends exit opposite sides.
Strength/Reliability
The Offset Figure Eight Bend is not a very reliable bend and should be avoided. When the ropes are pulled in opposite directions it can cause the knot to distort and become unsafe — unlike the proper Figure Eight Bend.
Warning
Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.
Common Uses
- join two ropes together (not recommended due to poor security).
