Forcing a Patina on Cruwear!
Why?
Because I’m going to the sea and I just need to be certain it won’t pit.
Now Cruwear seems tricky compared to 52100 or Maxamet.
Let see how it will get…

 

45 minutes later… No patina yet some stains…
“It’s not as rusty as 1095 usually, so it’s easy to get complacent. It can go 3-4 days easier than O-1 or 1095 but 3-4 months is a different story. It’s easy to get fooled by steels with this level of chrome ( 8%) as to corrosion resistance. It will appear as a tiny spot of rust. Easy to overlook as it does not make it apparent that spot is deepening, not getting wider. The surface layer of rust covers up the hole. ”

And he was right…

Trying to mix oxygen and vinegar using tissues and apple vinegar ?… Nope.

Apple vinegar and apple sugar under the sun….. Nope.

Aceto di Modena…. nope.

Even in the wind…

Naaah forget it. This steel won’t stain beautifully… Just a bit but not enough in my taste.
It will perhaps pit if let unclean some weeks but in my daily uses it should not.

Putting the blade back in the handle the tolerances on that knife are so great you can tight the screws with locktite and pur a drop of nano oil… the pivot is smooth as butter.
Also ten passes on white ceramic and it is back to jumping hairs harvest again.
So cruwear seems to be a very “friendly” steel which doesn’t smell anything when confronted to apple, apple vinegar, various vinegar including aceto … nothing seems to harm it surface.
It is like CPM 3V and will be kept oiled and shiny. My Ed Schempp’s Tuff never needed or develop a patina as my grey Military in Cruwear.
At least I got less worry. 🙂
