This US Model 1917 Bolo knife by Plumb is dated 1918. It has a black blade with mirror polished edges and sharpened top edge (the mirror polished edge is not original, but looks really good), .246" blade stock and 2.108" blade depth, full tang construction. The handle has a steel guard and butt with wood scales. Comes with original canvas covered metal scabbard. Scabbard is in really good condition considering this knife is 100 years old. Has some dings and scratches, but overall in really good condition for a 100 year old knife.
