I am not familiar with farrier's tools but the wood part has many powder post beetle holes in it. This is real common but just make sure there are not active beetles in the wood before bringing it inside your house. I usually fill the holes using a syringe filled with watered down white glue to seal up the old holes and then seal the wood in a bag for a period of time to see if any live beetles emerge. Any fresh powdered wood dust and you have new activity. You do not want active powder post beetles in your house.
