|Figure one. Scottsbluff knife form from Wilson County, Texas. The most |
interesting feature on this 8,500 year old beauty is its burinated tip.
|Figure two. Burin tip of the Scottsbluff knife form |
pictured in Figure one. Note the stop notch below burin.
This stop notch was to ensure burin did not travel further
down the edge of the knife.
Most burins and burin spalls were unspectacular. Most people do not even recognize them. Caution is needed in identifying the difference between an impact fracture and a burin. Burination strengthened the tip of this Scottsbluff point exponentially, keeping the edge from failing as it would ultimately do if left sharp.
