Used by the Late Paleo Agate Basin Peoples strictly as a knife, not meant to be a lance tip, but sharing the lower lateral edge grinding of the lance blades--and the basal thinning (almost a flute) you'd see on an Agate Basin lance--definitely hafted, though. The creek find is a northwest Kentucky piece, water & mineral stained to a heavy degree. the flint is a higher gloss flint, but not an Indiana hornstone-type flint, there is more color variation--partly due, naturally, to some eight--nine thousand years on creekwater, Give any flint that much exposure, the color isn't going to be what the 'raw' flint looked like. Length is barely under 3&5/8" by 1&1/8", with a very thin profile--my caliper can't find a (quite) 5/16" spot--thin, artistic workmanship. One sure sign of both the thinness and the flint quality is that when set down on another piece of flint that "tink' sound rings out. Good flint does that. Every detail is lifetime guaranteed authentic, period. Shipping comes with the price. I welcome checks or M.O.s, but lease note I do not use paypal--Roy A.
