The head on most axes or splitting Mauls will have an edge that is made out of either steel or high carbon alloyed steel which has been tempered at least five times for added hardness. The very sharpened end part of these tools is known as its blade while the opposite side with notches in them would be called bit (the spikes). In between both sides there is what we call a poll where many people like to attach rope handles onto when using their wood splitter because they provide more leverage and control. Finally, the end of each handle is attached to a steel or wooden wedge that helps split logs even further!
