Force Patina?

Sargent 666 said:
So you dipped it in an acid solution up to the bolster (or removed the blade) and it didn't discolor the etching (graphics)?

I've used a lot of D2 and never had any patina in normal use.

I've never tried to force it .... I'd rather use them to do it than let it sit in a glass.

I took the blade out, but the coverage was a bit spotty at the pivot end; need a deeper glass.:)

The acid actually improved the graphics; you couldn't actually see them before, because I had done a big sanding job on the blade in an attempt to get the rust pitting out of the blade (the last guy brought it with him to Peru, and left it in the luggage un-oiled, hence the rust).
I was surprised at how the etching came out with the acid treatment.:thumbup:
 
I got this with mustard, hot sauce and ketchup. 1095.
Won't try it with my Para D2 though as that baby hasn't rusted stained or anything in a year!

Wow! Is it straight D2 or CPM?

Have you already said what you used to treat it ...

Either way ... it looks good!:D

Those where CPM.
I'm wondering if there is any differance in it and reg D2 at staining/rusting, or taking an etch or patina? I wouldn't think so, but have no idea really.



bigmo66, thats a great looking patina:thumbup:

Thanks!:)
It's CPM D2, but I doubt that affects the stain resistance. I think the powdered metalurgy is supposed to give a finer grained steel though, if I remember correctly.
Oh yeah, I used lemon juice for this one. I tried vinegar, mustard, and hot sauce, but those didn't do a whole lot to it.
The lemon juice sure did though.
 
ive used rice vinegar and its either given me a nice light blue patina, or become almost as black as some phosphate paint, only tried it on a bunch of random carbon steel blades though

lemon juice huh...

and the cpm process should [theoretically] increase stain resistance by evening out the grain structure and getting a nice even distribution of the chromium content of the steel... just a thought.

i'm not big on taking it apart seeing how benchmade feels about that in regards to their warranty... best way to patina it without dissembly?

I suppose you could soak the knife assembled, and just wash it out really well, then oil the hell out of it afterwards.
The pivot and such should be full stainless, and even lemon juice won't touch that stuff (I tried).
 
I have a Mini Bone Collector that I got a few months ago.

I'm really tempted to disassemble her and try this.

Real juice from real lemons or the stuff in the plastic lemon thingy.:p:D

I'll be looking forward to the results!:thumbup:

Wondering if roughing up the finish makes a difference.

I might have to get a case of Corona and a bag full of lemons this weekend!:barf::D

lmao... can't wait to get the HEST folder for my party knife!! :thumbup:

so much more satisfying to use a bottle opener, especially on a knife :D

If citric acid is the active ingredient that causes the patina, I don't think the "real lemon" juice will work for you. The "real lemon" juice doesn't have any citric acid in it.
