I am still learning sharpening. There is always a new tool to learn what to do with. I am just glad that when I am being the most frustrated, I normally get told now that someone with more experience did not do any better.
Axes are something I have just added to my repetoire. The surge of throwing axes as a support has meant more axes need care. I do not do all the care yet but I do sharpen them. My Beloved actually joined a league. Koda Bear wants to but is not old enough so he practices in the backyard and scorekeeps on Sundays. I just laugh. I usually drive over with them and walk home. It is part of why my life keeps getting busier. I am not going to turn my nose up at business!
One of the next things I am going to learn to sharpen are clipper blades. I actually need to do that out of town but I will schedule that after the next trip to my Dad's. Small steps.
