i was croosing a stream on my ground that was swollen the past few weeks and got a chance to cross finally and in the sand i noticed something so i picked it up and low and behold a cobb knife arrowhead 6 inches long and perfect condition, i put it in my pocket and continued to the stand when i got settled in i reached into my pocket and sat there and smiled for a couple of hours, didn't see any deer but had one of the best times i have had in a long time. here i am with this modern weapon looking at the past on the same ground that they hunted deer and turkey on looking on the web i find cobb knives range from 7500 bc to 4500 bc in age not like native Americans with bows and arrows but stone age man type tools some of the arrowheads are 4 inches long and up to 3/4 inch thick i am not a arrowhead hunter i just happen appon them .
