Yoshihiro TSOIL 100% Pure Tsubaki Japanese Knife Maintenance Oil With Complimentary Sabitori Rust Eraser, 3.4 oz, Large, Golden Yellow

And that is no exaggeration: this knife oil--I know it by the name "hinoki"; there are other names for it--is bsolutely fantastic for knife blades. Living in the high desert, rust isn't much of an issue unless one is careless with one's knives, but regardless, it's always a good idea to protect blades with the application of oil periodically. This oil is perfect: viscous enough to stay whete you put it but light enough to be easily spread on the blade; it dries quickly without leaving a sticky residue, yet blades that have been treated will resist fingerprints and repel dust for days. I love shiny, satin finish blades, and I love the even shinier mirror finish blades when I can find them, but they are susceptible to finger prints when handled. Leave those print on a shiny blade long enough and the acidic skin oil will permanently discolor the steel. Satin/mirror blades that have had this oil applied, however, behave like stonewashed blades, i.e., they will not pick up finger prints at all. It's really quite remarkable and wonderful. One more positive feature of this oil: it can be applied to blades with a partial black coating w/o staining the coating. In other words, the plain metal portions of a blade that need oil can get it, and the black coated portions aren't left with a big, greasy smeer. Ok, one more great feature: I've treated +50 knives in the week I've had this oil and the volume in the bottle has decreased maybe...10%? Maybe less, depending upon exactly what the fluid level looked like when I got it, which I dont recall. Oh, and the eraser works great too. With a little patience it took off some patina spots that had developed on a CPM M4 blade I have. But the eraser is just a normal-good product. The oil is one of the most phenomenally outstanding products I've used, ever, period.

Perfect product for high carbon coating, has lasted months on my blades, with good care, the occasional inspection and just a few drops of this, my blades are ready to take a good nap without fear of rusting.

Nice product.

Exactly what it says it is

I am super glad I found this product! A few months ago I found this roll of Damascus steel knives in a box of free stuff. Three of them were in perfect condition the other two as you can see were not cared for properly somebody must’ve washed them and not dried them immediately and rust developed. After figuring out that these were $600 knives I was on a mission to restore the two rested knives And this product worked marvelously! There are still some imperfections because of the amount of rust, but after using the rust eraser I can definitely get a buffing stone and buff out the rest of the imperfections easily! This was super easy to use also
