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.
