wow Jim, what a stash that is. don't find many double bits here, i did get one from an old barn they were gonna burn. its on the small side and has a chip out one side. i should clean it up to see who made it.
just occurred to me.......if they shipped hundreds of tons of iron bar in the 18th century, it took a terrible amount of charcoal to make it. what happened to all the axes? we did find a crosscut last year near a coal pile. it was not worth trying to save.
