The '''Yakutian knife''' (Sakha: {{lang|sah|саха быһаҕа}} ''Sakha byhagha''; Russian: {{lang|ru|якутский нож}}),  sometimes called the '''Yakut knife''', is a traditional knife of Yakuts (an ethnic group from the [[Biography:Sakha Republic|Sakha Republic]] (or Yakutia), region of Siberia), used for working with wood, hides, skins, fish and meat or for combat. The knife has been used in Yakutia for hundreds of years without significant changes in its design.<ref>''Arctic Pastoralist Sakha: Ethnography of Evolution and Microadaptation in Siberia''</ref>
 
Typical Yakutian knives have a blade length of {{convert|4|-|7|in|cm}}, and {{convert|1|-|1+1⁄2|in|cm}} wide. An unusual feature of this knife is that the blade is asymmetrical; one side of the blade has a [[Engineering:Fuller (weapon)|fuller]], that is a groove in it and a chisel grind, while the other side has no groove and is basically a convex edge (meaning it rounds down to the edge, rather than having a straight [[Bevel|bevel]]).<ref>[https://warriorpublications.wordpress.com/2015/01/14/knives-of-the-yakut/  Knives of the Yakut]</ref>
The blade is traditionally forged<ref>[http://terraoko.com/?p=88440 How do Yakut knives]</ref><ref>[http://www.thetruthaboutknives.com/2015/12/forging-a-siberian-yakutian-knife/  Know your Knives: The Yakut knife of Russia]</ref><ref>[http://siberiantimes.com/other/others/features/f0197-forging-knives-like-our-ancestors-secrets-of-the-yakutian-blades/  Forging knives like our ancestors, secrets of the Yakutian blades]</ref> from locally sourced [[Earth:Iron ore|iron ore]] smelted by Yakutian [[Engineering:Blacksmith|blacksmith]]s. The groove in the blade makes it lighter and allows the blacksmith to reduce the amount of metal needed to make larger knives.  The knife handle is historically made from [[Biology:Birch|birch]] [[Biology:Burl|burl]] and is thick and [[Oval|egg-shaped]] in cross-section. It fits the hand and can also be used wearing gloves. The birch also protects the hand from the cold effects of the knife steel in extreme cold, a common condition in Siberia during winter months. A cow [[Biology:Tail|tail]] knife sheath completes the ensemble.
