There is nothing like making your own handle installing it, and then learning the skill of broadaxing, and getting to know the feeling of the curvature and sweep of your creation, I suggest trying it it is not as hard as you might think.
A boughten handle does not contain the little things that mean much when it comes to handles, I am referring to when you grasp the handle you can feel the irregularities, along with many different things.
You can be part of the process as I work along from start to finish.
