The '''Eskimo bowline''', '''Cossack knot''' ({{langx|ru|Казачий узел}}), reverse [[bowline]], or 'anti-[[bowline]]' is in a class of knots known as 'eye knots' or '[[loop (knot)|loop]] knots'. The [[List of knot terminology#Eye|eye]] is formed in the end of the rope to permit attachments/connections. It is quite common in Russia and is often used instead of the [[bowline]] (ABoK #1010). In the simple bowline, the '''collar''' component forms around the 'standing part'. In contrast, the collar component of an Eskimo bowline forms around the outgoing eye-leg.

On the first of arctic explorer [[John Ross (Royal Navy officer)|John Ross]]' expeditions (1818) the Inuit (Eskimos) presented him a sled that contained several of these knots, showing that it is a genuine Inuit knot.<ref name=Bud />
The knot is not mentioned in ''[[The Ashley Book of Knots]]'' but in its Russian equivalent, the book "Морские узлы"

(Marine Knots) by [[:ru:Скрягин, Лев Николаевич|Lev Skryagin]] (1930–2000). The knot is referred to in the Russian book as the Cossack knot, and its slipped version is known as the [[Kalmyk loop]].

The Eskimo bowline is about as strong as and even more secure than the [[bowline]],<ref name='Com'>{{cite book|first=Nic|last=Compton|title=The Knot Bible|publisher=Adlard Coles Nautical|year=2013|isbn=978-1-4081-5476-2|page=83}}</ref><ref name='Bud'>{{cite book|first=Geoffrey|last=Budworth|title=The Complete Guide to Knot and Knot Tying|publisher=Lorenz Books|year=2001|isbn=0-7548-0422-4|page=179}}</ref> especially in synthetic lines.

Under cross load (ring loading, transverse loading profile), i.e. when the loop is pulled apart, the shown common Eskimo loop effectively mimics an ends-opposite (and inferior) left-hand [[sheet bend]] and thus can slip like the bowline; the less common Eskimo loop variant with the A–C loop (see bowline family diagram) would give a proper same-side [[sheet bend]], thus being much stronger under cross load. Similarly, when the eye of a simple Bowline is subject to a transverse loading profile, it mimics the inferior version of the [[Lapp bend]], and so can slip and untie; the wrongly demeaned left-handed or [[cowboy bowline]] becomes the proper Lapp bend, and should hold.{{Citation needed|date=April 2018}}.

All of the maneuvers to tie this knot are generally in the opposite (or 'anti' direction) relative to the [[bowline]].
 After forming the 'nipping loop' with C & D (which can be formed as 'S' or 'Z' chirality) the working end is fed through that loop from the same side A as the outgoing eye leg C. This is opposite (or 'anti') direction relative to the simple (#1010) Bowline (A–D on opposite sides).

The so called 'Eskimo' Bowline has also been known as ''Boas Bowline'' and ''Cossack knot'' - all of these names referring to the same structure. The [[Kalmyk loop]]<ref>{{youtube|wgJc1ymlYgg}} Tying video for Kalmyk loop</ref><ref>{{youtube|3Bl31rAWTcI}} Tying video for Kalmyk loop</ref> can be made 'TIB' (Tiable In the Bight); however, it will not be 'EEL' (Either End Loadable).
