Figure-of-nine loop
type of knot
The figure-of-nine loop is a type of knot to form a fixed loop in a rope. Tied in the bight, it is made similarly to a figure-of-eight loop but with an extra half-turn before finishing the knot.
Also similar to the stevedore loop, the figure-nine loop is generally shown as being based on an intermediate form between the figure-eight knot and the stevedore knot. The Ashley Book of Knots shows this intermediate knot, in stopper form, as #521.
While it uses more rope and is bulkier than the figure-of-eight loop, the figure-nine loop is somewhat stronger and less likely to jam. It is sometimes used instead of a figure-of-eight loop to attach a rope to an anchor point or belay.
Tying
Figure-of-nine knot
The knot can also be tied with the end of a rope - a single strand replaces the double strand, and therefore a naked end replaces the loop. This knot can be rearranged to form a stopper knot, in the same manner as a figure-of-eight stopper knot.
The public source identifies “Figure-of-nine loop” as type of knot. This brief keeps that definition visible, then builds a research path around Figure-of-nine, loop and type.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Figure-of-nine loop”, the useful work is to connect “type of knot” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 20, 2024. The linked authority identifier is Q1516669. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
