Oversize 6+ inch Spalls - Large Flat Rate Box - Free Shipping

Limited time offer for rare oversize material while supplies last. Large USPS Flat Rate box packed with 20 pounds of our #1 graded and cleaned 6+ inch 'extra-large' spalls. Box price includes shipping within the domestic United States.

These 6 + inch 'oversize' spalls are ideal in size for producing large points and blades. Material of this size and quality is rare, and we do not regularly offer oversize in our product listings. For a limited time we are liquidating some of our personal stock in order to make room for new inventory.

This size and grade of material is best for the seasoned knapper with advanced knowledge of how to get the most out of large material. Priority Mail Postage within the United States is pre-paid and included in the price of this 20 lb box of Spalls.

International Customers: The large flat rate box is not available for shipment due to an international weight cap on this size box. Please contact us for alternative shipping options. 

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.

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.
