thats what i call them anyways tha hook shaped one is interesting what say you knappers are these just random flakes they are extremely sharp on the edges
I am just beginning to learn about flintknapping and have only gotten as far as knocking flakes off a large cobble, but I can say for sure some of the flakes I've knocked off are extremely sharp! I'm talking scalpel sharp - yep plenty of band-aids have been used lol!
i believe those razor sharp flakes were used a great deal i save the better examples that i find i also save some of the bigger chunks with the thought of giving them to someone who could use them for knapping material
