This Folsom ultratin knife is a rare offering.  It is made of Knife River 'flint' (silicified lignite) from North Dakota; a favorite material of Folsom knappers.  These are particularly difficult to make because of their thinness.  This piece is 81.5mm long, 56mm wide and only 5mm thick.  It has a W/Th ratio of 11.2/1.  Made by Bruce Bradley 17 February 2021.
