Any way to find out a date I purchased items from HI? Seems I dropped off the forum somewhere around 2015, and just got around to looking into my old bookmarks. Had brain cancer, surgery, etc. and have been dealing with that, physical therapy and money/job issues. I've finally got things sorted out, mostly. But I have this fairly large collection of, what I'm told, are HI blades made in Nepal. I like them. But I don't remember buying them. Or, for that matter, being a member here. (Lots of things I don't remember, but that's a whole 'nother story!) But it seems my computer remembered. Couple are a bit rusty, and one's sheath has split. Best methods for cleaning them up?
