If not proficient at honing I would send out to a pro for honing a family heirloom. Its not that hard screwing up a blade by not knowing what you are doing, trust me, been there, done that! I was lucky it wasn't a family heirloom that I screwed up.

As far as the clean up goes, Mothers Mag & Aluminum Polish should take care of the blade. A toothbrush and some mild soap or toothpaste should take care of the scales. Dental floss works for around the pin and pipe cleaners work well between the scales.

Good luck and enjoy!
