So I got my first ever Swiss Army Knife 2 months ago. It’s a Victorinox Huntsman with 14 tools (the one with the saw). I have not used it extensively yet, but I wipe it clean every time I use it.
I’m not aware of when and how often I should oil the moving parts and things like that. I would like to keep this knife in working condition for as long as I can.
I have one of those monsters with everything in it and my maintenance is wiping it off if it gets something on it. I think I might have put some WD-40 or bike chain oil on it one time. I might have sharpened the big blade once.
