This is a traditional Siberian hand forged Yakut /Evenki knife.
BLADE: 4 3/4" long Forged 52100 high carbon steel. Thickness 5 mm.
Handle: 5 1/2" long Acacia Wood
The sheath is crafted from the traditional genuine leather and treated with natural oils and beeswax. (similar to pic)
The belt loop is crafted from a genuine Yakut horse hair braid and bone bead.
The Evenki knife's unique concave/convex geometry sets it apart from every other knife. http://av-salnikov.livejournal.com/2995.html
