Show Your Patina!

[3rdGenRigger]

Anyone ever see 440 develop a patina? After a few months of use my Seratta seems to have some patina and/or staining. I haven't tried polish, but that said I've scrubbed it as hard as I can and it won't move at all. It doesn't bother me at all, and I know 440 is less stainless than a lot of other stainless steels, but since I've never seen this on a stainless knife before I thought I'd see if anyone else has experienced this.

It looks very good! I prefer your patina over most "artificial mustard patinas". Thanks for sharing!

This is my Caly Super Blue I did with a grapefruit. I'm new to the Spyderco Forum but certainly not to the Spyderco brand.
Hope you guys like it.



I also did my Manbug with a Blood Orange

Newtron - those patinas are really nice! Are those two knives "users" or collection pieces?

So did you simply stick the blade inside a grapefruit? I really like the way it came out, but it looks like you need to sharpen the edges again.

Thanks guys :)
The Caly is a collector for me. I purchased it to use and put the patina on.. now can't bring myself to mess with it. The manbug I just got the other night and I suspect my wife will be adopting that one!

I started by sticking Opinels into fruits but found there was too much fruit acid. So for the Caly I cut a grapefruit just off center, pat it dry it with paper towel and sandwich the blade between the fruit slices for 15 to 30min. And thats about it.
The manbug I did with a Blood Orange, but same procedure.

The edge is still fairly sharp. They don't take quite the same beating as a FC acid etch. I could throw them on the WE... but I'll probably just touch them up on the ceramic sticks

My Stretch after 1 day. Just cut some fruit and already a nice look. Beside is my 1095 GEC with a little more than a months patina forming.

That picture makes it look pretty thin behind the edge. It might just be lighting because the bug is still there.

It used to be a lot thicker before I convexed it... The bug took a few shots but survived the ordeal. Here is a before pic with other M4 friends. At this point it had a 28 deg incl EP bevel, same as the Bradley but notice how much wider the bevel:

The patina seems to hide the imperfections. I think it looks pretty good.

I kind of figured that's what could have been done.

Thanks Donut... The convex turned this into my farourite Military... Here is a final patina pic I took a while ago:



These superblues are also thin with natural patinas:

The manbug I did with a Blood Orange, but same procedure.

So impressed I bought a SB Manbug today so I could have a go! No oranges here so might try a lemon or mandarin, just have to inspect the "grain"

Been away a while and I missed you guys. The super blue is still making me happy day in and day out.
