Very cool. I use it on any stainless I have, even food knives. What I do is spread out a good few drops all over a blade and spine of the tang and let it sit for 5-10 minutes then wipe the excess off and let that set overnight. Then I take a polishing cloth and while I do my morning YouTubing spend 30 minutes or so getting a nice polish on them and it’s done. Legit makes everything easier. The great part is it will seal if you wipe away. Then, on my folders and autos I just drop a liberal amount into the action and don’t wipe. One big perk on joints and springs and stuff is it’s resistant to very high heat and repels water and dirt wayyy better then say a mineral oil, that seems to attract fix and garbage into the joints.Been using EDCI on A11 Mule for over a year with good results! I apply a quick application once a week when in use, Mostly on RV trips! My Bottle (couple years old) doesn't have food safe anywhere on label!
Tuf-Glide is awesome for me but I see where people don’t like it cause way more expensive when compared to other tool oil.
Even used it on a nice outdoor hinge that gets abused by heat and water constantly and tuf glide once did what wd-40 once a week did but no runny mess on the door. They sell a small pen version with a pocket clip and if you are careful you can do an entire collection and have some leftover.
