This listing is for a small flat rate box of Kentucky hornstone flint! I picked this flint up while hunting arrowheads. The largest piece is 9" long and 5 1/2" wide, and I always fill the box with flint before I shipping it. A box of this flint costs me $10.40 to ship, and they weigh around 4 pounds more or less when shipped. This flint works very well and the Indians made many artifacts and tools out of it. I have found several blades, one over 10" long in this field while hunting, and even some flint hoes. This flint needs no heat treating to work, and it is easy to spall out. If you have any questions I will answer them. ***P.S. Buy two of these boxes, and I will combine them into a medium box. That way you will get "more flint" with your purchase!
