Probably one of the most important tools that you can have if you are hewing the logs yourself. Hewing is basically the process from taking a round log and making a flat edge. This is essential with stacking the locks on top of each other to build your wall. A broadaxe is used in the final steps to create a much smoother edge to the log for stacking. You have to make sure its smooth and very flat and the broadaxes’ large sharp one sided blade allows you to cut a smooth side to a log. Check this video out because it actually shows you how you can hew a log completely with a broadaxe. This guy does it pretty quickly but you get the idea. If you want to make it more pretty, just take your time with it.
