Terminology and fishhook anatomy.  Fishhook is an item for catching fish. These ancient examples are from Florida waterways and while at first glance appear much the same. Closer inspection reveals diversity and unique features crafted by skilled artisans. Florida fishhooks tend to be eyeless. Instead, they have grooves on this portion of the upper shank.

Eye/Eyeless:
