I think it is a homemade hookaroon, alot of oldtimers would make them out of old axes we call them tie picks around here, used to pull flethes and lumber from sawmill rollers, move logs around and what ever else came up. you can buy them new ,just look up Hookaroon. Another use for the same style is a dogging hammer, used to drive skidding dogs into logs ,and the pointed end to pry the dogs loose.
