The other tomahawk is a spike poll type. I have no idea of its date of manufacture. It was given to me many years ago. According to "Fur Trade Tomahawks" http://furtradetomahawks.tripod.com a child's tomahawk/axe is distinguished by the head being less than 5 inches long from the poll to the cutting edge. Both these tomahawks below conform to that size. I am not claiming that these two tomahawks are exact copies of originals, just that they are the same size as a child's tomahawk.
Here you can see a comparison between my wife's belt axe and the smaller tomahawk/axe.
My youngest Son when only very young. You can just see the tomahawk helve sticking out by his left hand. The knife in his belt is real too.
