Making a wooden board from a log with one single axe - The Medieval Way

This is how I make wooden boards using only one single axe. Well, to be honest, in the beginning I use a small carving axe for making a wooden wedge. Both axes shown here are fitting for Central European medieval ages.
The log, red oak (quercus rubra) was already split in smaller sections, you can see the bigger halfs in the back. I also tried to avoid using clamps or hooks to fasten the board to go full rural medieval, so it's hopping around quite a bit. The oak was more twisted than I hoped so I actually had to remove quite some material and got a pretty narrow board in the end, but thats always the difficulty with splitting logs.
In the end there are some shots of the finished building where the boards were used for a simple wall. It's a workshop shelter with a greenroof, currently equipped with a medieval forge. Look at the textures from the axes!

Edit:
To make it clear, the aim was to use one single axe for all steps involved, meaning using an axe that could also be used for felling a tree, splitting and hewing. In rural medieval villages, where tools were expensive and people probably rather went for tools that could to a lot of tasks than tools that can only do one specific task. And off-set hewing axes are only for one job good: making plane surfaces.
