No worries. Thanks Jon.
That's about what I reckoned, and of course I'm sure the heat treatment protocol has much to do with reactivity as well. Thanks again!Cambertree wrote: ↑Tue Jun 18, 2019 10:26 pmNo worries. Thanks Jon.
I’ve had all three of the K390 releases so far (Edgematters Pingo, Urban, Police).
I find K390 to take a patina readily when new - it’s only slightly more corrosion resistant than the simple carbon steels or 52100 and Superblue.
In terms of the non stainless steels I have in Spydies, and how quick they are to patina, I’d rate them roughly as follows.
52100 and Superblue.
I just treat K390 the same as a simple carbon steel blade, regarding maintenance and oiling.
I don’t tend to force patinas, although I do intentionally use new non stainless knives on food prep like slicing and peeling fruit and veg, until the patina is well established.
Thanks! Sorry, I just now saw this. Yes, it is the Cutlery Shoppe exclusive Endura in HAP40.
Huh, that's very cool, I've never seen a sulphuric acid patina before. Did you just wipe it over with a paper towel or something? What sort of solution did you use?PeaceInOurTime wrote: ↑Mon Sep 23, 2019 8:28 pmThanks! Sorry, I just now saw this. Yes, it is the Cutlery Shoppe exclusive Endura in HAP40.
I started out just letting it naturally patina, which was coming along nicely, but then I decided to see how it would look using sulfuric acid over the entire blade. I'm happy with the results.
Lookin' good Woodpuppy, and that's a great pic of an awesome pair of knives.Woodpuppy wrote: I finally gave in and decided to let the patina donuts thing on my M4 para3
I just "blotched" it on the blade using a small cotton swab several times until I was satisfied with how it looked. I suppose wrapping the blade in a soaked paper towel may have produced a more uniform pattern, may have to try that with another knife.
Now that is one nice little piece you got there!
