This is a simple tool whose origins lie in the dim past. A froe is suitable for splitting kindling through to splitting laths for hurdles etc. The two benefits are that unlike an axe where you are stuck when the head is below the wood when splitting through, the Froe sticks out and you can continue down the stave. The second and most important, you stand a good chance of keeping your fingers. There is a video of one in use on Facebook. Search for Deerwood Products.
