I had a couple handles for cold steel tomahawks laying around and found that they can be made to fit pretty easily. These axe heads have a slightly smaller eye than the cold steel tomahawks so there is a decent amount of wood to get a good friction fit. Below is an H and a K1. I still have some fitting to do, but I'm happy with it. Happy enough I ordered a couple more of each. Should be good for throwing with the kid when he gets older.
