A bit off topic

I just learned that if you stick a chrome vanadium blade in an apple, it will take on a patina making it look old, in about an hour. Personally I like the look of carbon steel blades that have that grey/brown patina that comes with age. I just got done "aging" a Case Chestnut bone medium stockman with CV blades, and I'm pleased with the results. I also read that this actually makes the blades less susceptible to rust.

Does anyone know anything more about this? Anything I should know before I go hog wild and "age" all my Case CV's? They're all "users" obviously.

Hey Jim,

Anything acidic will do it. Citrus, mustard, soft drinks, vinegar, whatever. If you want it to happen fast, put some apple cider vinegar in the microwave until it starts to bubble up....sumberge the blade, and wait for the depth of color you prefer. Some carbon steels react differently than others, and for the most even patina, the knife should be squeeky clean.
However, some cool patterns will still emerge with most carbon steel.

As far as rust, the black oxidation will ward off red oxidation (rust), except on the cutting edge.

Once again, thanks Bill. You're a wealth of information and expertise as usual. Not to mention patient with my newbie questions.

If you'll permit me another -- after I read your response I tried it with boiling apple cider vinegar (I had some) and indeed the blades turned almost black. Still pretty cool looking.

I've heard of "Parkerized" blades without ever knowing anything about it. Is this what I've done, or is that something different?

Regards,

Jim

You're going to get me soon here.....and I'll be speechless.

I knew that Parkerizing was similar, but more durable than black oxide.....but I couldn't explain it exactly. Sooooo.....

Note the final paragraph, I guess that makes black oxide sorta like the not quite developed little brother (no offense to any little brothers.. ).

By the way, if you pick up a product called NEVR-DULL in a silver can (WalMart, Auto stores), it is a wadding/polishing material, you can tear off a little and use it to smooth the patina a bit. If you don't want it to be too black, take it out quicker. You just have to experiment a bit. If you do one you hate, get after it RIGHT AWAY with Flitz or Mother's Mag polish, it should come off OK.

Happy Patinazing (new slang, sorta like Bling),

All I can say is wow. Thanks again!

Bill, is always right on in this forum. I have used never dull for years and it is by the far the best for me. My wife has found a hundred uses for it too.

BILL, keep up the good work.

Thanks for the kind words. I just enjoy this stuff.
