Imagine a band of Paleo hunters successfully taking down a tusk-wielding mammoth.  They brandish their fluted clovis knives and begin the task of butchering the monster which will provide food, clothing and much more for their families.  As they work, one hunter slices off a piece of raw meat and takes a bite.  He thrusts his knife skyward and screams victory, mammoth blood running down his chin and his knife. 

 I see this clovis blade as that moment frozen in time!
