A mix of hornstone and Perry County, Indiana Derby Flint along with a couple that are made of river pebble red Jasper--easy to recognize those. The longest point is a hornstone snap base (salvaged and basal edge polished by the Woodland user) Buck Creek type, not quite to 1&3/4"--very thin for the length. The Derby Flint Turkey Tail is another heavily used and salvaged point, 1&7/16". The mottled color bifurcated Kirk Stemmed is another very thin piece--the flint may be in the Spencer County, Indiana "Holland Chert" family, and that's as close as I can classify it--unusual color for Holland, but ancient hunters, tracking deer through area creeks would stumble on flint outcrops, haul some home for the village knapper--maybe they went back for more, but often a few pieces would be found on a site and that one "I'll try it" was enough. ALL ten are guaranteed real, they come from an Evansville, Indiana, area collection. Shipping is $8.00 with payment by only three methods: check, cash, or money order--I do not use payment services (like paypal)--Roy A.
