Brummel Structure: The animation shows how the Locked Brummel Splice can be tied when both ends are available to be threaded through the rope. In practice, using a fid makes the process easier, especially when passing the long buried tail up the center of the standing end.

Warning: in practice use a much longer tail and a more gradual taper – see below. The short ends were used here to allow close-up photography.

The Brummel Lock: When completed, the two parts of the splice lie closely against each other to make the lock. However, the lock distorts the fibers and would lower the breaking strain if used alone.

Strength: The intended strength is derived from the tail being tapered and buried through the center of the standing end – which exerts a powerful gripping action under tension; the force in the standing end is progressively shared between the two lines. The final strength of the Brummel Splice should be 90 – 100% of the rope’s breaking strain.
