The
blade of the Yakut knife is sharpened, has a cutting edge on one side and a straight (or almost straight) spine. A distinctive feature of the Yakut knife is the asymmetrical sharpening of the blade, noted by the first researchers of the life of the Yakuts. On one side, the blade of the knife is flat, has a fuller (if you look from the spine, then the right side of the blade). The opposite (left) side of the blade is curved. This is done so that when working with the knife, the knife does not "dig" into the material. It is in this regard that knives differ for right-handed and left-handed people. For left-handed people, knives are made with a mirror-inverted asymmetry of the blade. Knives are classified by blade length: • 80-110 mm - small knife (
byhychcha ). Usually made for children or women • 110-170 mm - knife (
byhah ) - the most common form • 170 - a large knife (
khotokhon - from the Yakut
khot - "to win") - practically a combat weapon, and therefore is rarely made • There is also a variation called “batiya” - a sword or machete, 500 mm long, with a curved blade with the same asymmetrical sharpening, mainly used as an
ice pick and for hunting bears. According to the blade width, there are tundra knives, which have a narrow blade, and taiga knives (alasny), which have a wider blade. In the tundra, the knife is mainly used for cutting or drilling, and in the taiga, for cutting up game and
livestock or working with wood. This explains the difference in blade width. Traditionally, a working Yakut knife has a blade made of fairly soft steel. Soft steel is dictated by practical considerations so that the knife can be sharpened in the field on river pebbles or other material. Recently, Yakut knives with blades made of special grades of steel or even
damask steel have become widespread. The origin of the fuller on the blade raises many questions among various researchers. There are various versions, starting from the fact that the fuller is needed for blood flow, that it is a tribute to the traditions when knives were made of bone, that the fuller facilitates convenient cutting of frozen meat due to the smaller contact area, that the fuller is needed to give rigidity to the blade, that the presence of the fuller is the result of the peculiarity of forging an asymmetric blade, or that the fuller is needed to reduce the weight of the blade so that the knife does not sink. == Handle ==
