I recently purchased a Rinaldi Milano Axe from @FortyTwoBlades shop Baryonyx Knife Co. He made a new handle in a 25" length to compliment the stock handle in 15" length. Funny thing is the custom handle fit far better than the stock handle the axe ships with. In fact, I was unable, or maybe I should say uncomfortable, trying to fit the shorter stock handle back into the axe head. The fit seemed so forced that I felt I could damage the original handle. This is how far it went without trying to finish pounding it in. Using a marking gauge and takeoffs from the better fitting custom handle, I began sanding the taper near the top. You can see in this picture the use of a leather strap to prevent marring the handle when tightened in the vise. The stock handle is pictured on the left. It had a much sharper taper where my fingers curled around the handle. I decided to use a drum sander on my drill press to knock it down to a more rounded finish. This picture shows the area along the ridge of the handle where material was removed. Next I hand finished the sanding to get a finer finish to it. I just pulled the paper back and forth like a shoe shine boy. Ready for insertion. The head dropped into place just by repeatedly dropping the axe handle on its top until I got a friction fit at the top. It will take a mallet striking the handle from below to remove the head. A nice superior custom fit and better shaped handle for my grip. A truly custom axe that I've made my own, with a little help from Benjamin aka @FortyTwoBlades .
