The lot features an interesting dag fighting knife attributed to the Sioux Native American Indians of South Dakota. The knife is marked “SORBY”. The handle shows a hardwood walnut, one piece handle with intricate, artistic pewter inlay cross, tipi, geometric, and saw tooth patterns. The blade itself shows a pointed, long, tapering double edge blade with prominent side notch cuts; it is marked on one side “SORBY”. The “SORBY” mark is attributed to I & H Sorby, a well-documented 19th Century English maker of dag knife blades, war lance blades, razors, and bayonets who supplied them to the Hudson’s Bay trade company and the American Fur Company in St. Louis. Similar examples of dag knives made from the remnants of war lance blades can be seen in “Early Knives & Beaded Sheaths of the American Frontier” by John Baldwin, 1997. The knife appears to be in good condition and in the style and manner of the 19th Century Sorby lances. Overall, the knife measures 15 1/5 inches in length.
