Just kidding.
I have a Norton three sided sharpening block something like this one, but mine is med, fine and really fine
That is a serious piece of equipment. When I lived in Tacoma, one of my neighbors worked for Weyerhauser. He had quite a collection of axes and had a larger version of one of those. I made sure I never got him mad at me. He kept them in a cabinet locked like you do with guns. And they were in a back room out of sight. Very few folks knew he had them.
In today's society, if the authorities saw that, they would probably confiscate them without asking questions and take him in as a potential terrorist.
