I use plenty of wood handled tools. Straight and axe handled splitters. I also have an all metal Monster Maul.
The main thing is to chip the edges and then work inwards. You are working harder and likely tearing out the grain in the handle near the head if you attack the middle and it doesn’t split perfectly straight. Everything has a technique that needs to be worked out. This is just mine, the way I do it.
Here is some oak the power company took down not far from me. I worked around to get to the middle rather than trying to bust it wide open with all my might. I kept this pace up for hours. I would split one, load it on the trailer, split another, load the pieces. This is at the end of the day and close to the end of the pile. Pretty lazy looking pace, but I never worked hard. This one I used the Monster. For smaller stuff I like my Council Tools with oiled handles.
