Keokuk Chert most often ranges in color from grey, pink and
tan with occasional bands of red and purple. Keokuk is a dense, high quality
chert found in parts of Oklahoma and surrounding areas. Next to impossible to
knap raw out of the ground, we digitally heat treat all of our
Keokuk within close tolerances in an effort to produce the most
consistently knappable stone achievable.
We strive to provide the cleanest, blemish free knapping
material within our means. On some spalls however, blemishes do get past us
because not all defects are evident at first or even second inspection. In
efforts to avoid defects as much as possible, we perform a few thinning blows to
ensure that you do not pay for large amounts of waste, over thick spalls, or
fragile/thin sizes that will shatter with the first strike.
Large knapping material requires large billets. Attempting
to knap large stone with too small of a billet will damage the billet and not
produce sizable thinning flakes early on in the process as needed. If you are
graduating to this size material from one of our kits, we recommend adding a
large copper percussion billet to your order. If you are unsure about what you
need, please visit our Flintknapping Buyer's
Guide, or feel free to contact us and we will
be glad to help.
