+1 I use the regular Tuff-Glide on every new knife. I use the small applicator bottle and let is soak in good, then use the Tuff-Cloth regularly
I'm like you, I use both my Police4 and (lots of) 52100 in south Louisiana, and if I keep on top of it I have no serious corrosion issues. You're right, 52100 is definitely Spyderco's hottest steel, but any ol' oil will do the trick!Haunted House wrote: ↑Mon Nov 04, 2019 11:37 pmI don’t have k390 but I do have a 52100 Para 3, and I believe 52100 is the most corrosive of all the Spydercos steels so far?
I live in the south (Georgia) where the humidity is wretched and carry this knife as a daily user, and I’ve had no corrosion issues so far.
I just keep a little Daiwa reel oil or gun oil(or whatever oil I have handy) on the blade and make sure to wipe it off after using it on anything liquid/corrosive. Easy money.
I also rotate between Cruwear and hap40 (which are also corrosion prone) and no issues with them either.
Just keep some sort of oil on the blade and wipe it off after use and you’ll be good.

I wipe everything off then wax the blade with a paste wax. I use Renaissance wax in particular. This pretty much keeps the blade oxygen free so rust will not build up. The wax also micro polishes the blade when applying so it helps clean the blade and really makes it look good. If I scratch or scrape the blade I reapply as needed. If I get salts/blood/acids etc on my knife I wash it off with soap and water and reapply. I also use dry aerosol teflon lubes on the pivot and bearing surfaces. It takes a lot longer to write about it than do it and this care keeps much rustier steel than K390 looking rust free and shiny.
