Found the hatchet I lost. Refurb advice needed

I have a Hults Bruk hatchet that I lost in a move a while ago. Needing advice on the best way to refurbish it. I have a Lansky knife sharpener I can use to get the edge back, if that would work. The handle is still stout but pretty dry. Not sure the best way to get it back to new-ish. Any advice would be great. Thanks.
